general description the max4711/max4712/max4713 are fault-protected, rail-to-rail , low-voltage analog switches featuring low on-resistance and guaranteed on-resistance flatness over the specified signal range. due to the fault protection fea- ture the analog switch input (no_ or nc_) and output (com_) pins are not symmetrical. the fault protection fea- ture allows for the analog input to go beyond the plus or minus supplies without the device drawing excessive amounts of current from the analog inputs. when the ana- log inputs are driven beyond the supply rails when the switch is on, it will sense a fault and turn itself off and the analog switch output will be clamped to the same polarity supply as the input signal and will not go beyond the sup- ply rails. this feature protects any electronic circuitry con- nected to the output from excessive voltages present on the analog inputs. the max4711/max4712/max4713 are quad, single- pole/single-throw (spst) analog switches. the max4711 has four normally closed switches (nc), the max4712 has four normally open switches (no), and the max4713 has two no and two nc switches. switching times are less than 125ns for t on , and less than 80ns for t off . these switches operate from a single +2.7v to +11v supply or from dual ?.7v to ?.5v supplies. all digital inputs have +0.8v to +2.4v logic thresholds, ensuring both ttl and cmos logic compatibility when using ?.5v to ?.5v or single +4.5v to +11v supplies. ________________________applications communication systems battery-operated systems signal routing test equipment data-acquisition industrial and process control systems avionics redundant/backup systems features ? fault-protected analog inputs ? 12v fault protection with power off ? 7v fault protection with 5v supplies ? +12v and -7v fault protection with +5v supply ? +12v and -9v fault protection with +3v supply ? fault-protected digital inputs may exceed v+ supply rail ? all switches off with power off ? rail-to-rail signal handling ? output clamped to appropriate supply voltages during fault condition ? 25 ?

max4711/max4712/max4713 detailed description the max4711/max4712/max4713 differ considerably from traditional fault-protection switches, with several advantages. first, they are constructed with two paral- lel fet? allowing very low on-resistance. second, they allow signals on the nc_ or no_ pins that are within or slightly beyond the supply rails to be passed through the switch to the com terminal, allowing rail-to-rail sig- nal operation. third, when a signal on nc_ or no_ exceeds the supply rails by about 150mv (a fault con- dition) the voltage on com_ is limited to the same polarity supply voltage. operation is identical for both fault polarities. during a fault condition, the no_ or nc_ input becomes high impedance regardless of the switch state or load resistance. if the switch is on, the com_ output current is supplied from v+ or v- by the clamp fet? that are connected from com to each supply. these fet? can typically source or sink up to 15ma. when power is removed, the fault protection is still in effect. in this case, the no_ or nc_ terminals are a vir- tual open circuit. the fault can be up to ?2v. the com_ pins are not fault-protected, they act as nor- mal cmos switch terminals. if a voltage source is con- nected to any com_ pin, it should be limited to the supply voltages. exceeding the supply voltage will cause high currents to flow through the esd-protected diodes, possibly damaging the device (see absolute maximum ratings ). pin compatibility these switches have identical pinouts to common non- fault-protected cmos switches. care should be exer- cised while considering them for direct replacements in existing printed circuit boards since only the no_ and nc_ pins of each switch are fault-protected. internal construction internal construction is shown in figure 1, with the ana- log signal paths shown in bold. a single no switch is shown; the nc configuration is identical except the logic-level translator is inverting. the analog switch is formed by the parallel combination of n-channel fet (n1) and p-channel fet (p1), which are driven on and off simultaneously according to the input fault condition and the logic-level state. normal operation two comparators continuously compare the voltage on the no_ (or nc_) pin with v+ and v-. when the signal on no_ or nc_ is between v+ and v- the switch acts normally, with fets n1 and p1 turning on and off in response to in_ signals. the parallel combination of n1 and p1 forms a low-value resistor between no_ (or fault-protected, low-voltage, quad spst analog switches 10 ______________________________________________________________________________________ pin description pin max4711 max4712 max4713 name function 1, 16, 9, 8 1, 16, 9, 8 1, 16, 9, 8 in1, in2, in3, in4 logic inputs. fault-protected to (v- + 12v). 2, 15, 10, 7 2, 15, 10, 7 2, 15, 10, 7 com1, com2, com3, com4 analog switch common terminals 3, 14, 11, 6 nc1, nc2, nc3, nc4 fault-protected analog switch normally closed terminals 3, 14, 11, 6 no1, no2, no3, no4 fault-protected analog switch normally open terminals 3, 6 no1, no4 fault-protected analog switch normally open terminals 14, 11 nc2, nc3 fault-protected analog switch normally closed terminals 444 v- negative supply voltage input. connect to gnd for single-supply operation. 55 5 gnd ground 12 12 12 n.c. no connection. not internally connected. 13 13 13 v+ positive supply input
nc_) and com_ so that signals pass equally well in either direction. positive fault condition when the signal on no_ (or nc_) exceeds v+ by about 150mv, the high-fault comparator output is high, turn- ing off fets n1 and p1. this makes the no_ (or nc_) input high impedance regardless of the switch state. if the switch state is ?ff? all fets are turned off and both no_ (or nc_) and com_ are high impedance. if the switch state is ?n? clamp fet p2 is turned on, sourc- ing current from v+ to com_. negative fault condition when the signal on no_ (or nc_) exceeds v- by about 150mv, the low-fault comparator output is high, turning off fets n1 and p1. this makes the no_ (or nc_) input high impedance regardless of the switch state. if the switch state is ?ff? all fets are turned off and both no_ (or nc_) and com_ are high impedance. if the switch state is ?n? clamp fet n2 is turned on, sinking current from com_ to v-. transient fault response and recovery when a fast rise-time or fall-time transient on nc_ or no_ exceeds v+ or v-, the output (com_) follows the input to the supply rail with only a few nanoseconds delay. this delay is due to the switch on-resistance and circuit capacitance to ground. when the input transient returns to within the supply rails, however, there is a 700ns output recovery delay time. these values depend on the com_ output resistance and capaci- tance, and are not production tested or guaranteed. the delays are not dependent on the fault amplitude. higher com_ output resistance and capacitance increase recovery times. com_ and in_ pins fets n2 and p2 can source about ?5ma from v+ or v- to com_ in the fault condition. ensure that if the com_ pin is connected to a low-resistance load, the absolute maximum current rating of 40ma is never exceeded both in normal and fault conditions. max4711/max4712/max4713 fault-protected, low-voltage, quad spst analog switches ______________________________________________________________________________________ 11 v+ no_ (nc_) in_ gnd v- high fault low fault on n1 p1 p2 com_ n2 nc switch -esd diode normally open switch construction figure 1. block diagram
max4711/max4712/max4713 the com_ pins do not have fault protection. reverse esd-protection diodes are internally connected between com_, and v+ and v-. if a signal on com_ exceeds v+ or v- by more than a diode drop, one of these diodes will conduct. the in_ pin can exceed the positive supply voltage, but they can go below the neg- ative supply by only a diode drop. the maximum volt- age on these pins is 12v if operating from a single supply, regardless of the supply voltage (including 0 volts), and if operating from dual supplies, the maxi- mum voltage is (v- + 12v). fault-protection voltage and power off the maximum fault voltage on the nc_ or no_ pins is ?2v with power off. in_ logic-level thresholds the logic-level thresholds are cmos and ttl compati- ble when using ?.5v to ?.5v or single +4.5v to +11v supplies. when using a +2.7v supply, the logic thresh- olds are v ih = 2.0v and v il = 0.6v. dual supplies the max4711/max4712/max4713 operate with bipolar supplies between ?.7v and ?.5v. the v+ and v- supplies need not be symmetrical, but their difference should not exceed 11v. single supply the max4711/max4712/max4713 operate from a sin- gle supply between +2.7v and +11v when v- is con- nected to gnd. chip information transistor count: 463 fault-protected, low-voltage, quad spst analog switches 12 ______________________________________________________________________________________ switches shown for logic "0" input dip/so/tssop max4712 logic switch 0 1 off on top view dip/so/tssop max4713 logic switches 1, 4 0 1 off on switches 2, 3 on off 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 in2 com2 nc2 v+ v- no1 com1 in1 max4713 n.c. nc3 com3 in3 in4 com4 no4 gnd 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 in2 com2 no2 v+ v- no1 com1 in1 max4712 n.c. no3 com3 in3 in4 com4 no4 gnd pin configurations/functional diagrams/truth tables (continued) part temp range pin-package max4712 cue 0 c to +70 c 16 tssop max4712cse 0 c to +70 c 16 narrow so max4712cpe 0 c to +70 c 16 plastic dip max4712eue -40 c to +85 c 16 tssop max4712ese -40 c to +85 c 16 narrow so max4712epe -40 c to +85 c 16 plastic dip max4713 cue 0 c to +70 c 16 tssop max4713cse 0 c to +70 c 16 narrow so max4713cpe 0 c to +70 c 16 plastic dip max4713eue -40 c to +85 c 16 tssop max4713ese -40 c to +85 c 16 narrow so max4713epe -40 c to +85? 16 plastic dip ordering information (continued)
