PI5C3384A
10-Bit, 2-Port BusSwitch
Product Features
Near-zero propagation delay Direct bus connection when switches are ON Ultra-low quiescent power (0.2A typical) Ideally suited for notebook applications Packages available: 24-pin 300-mil wide plastic PDIP (P24) 24-pin 150-mil wide plastic QSOP (Q24) 24-pin 300-mil wide plastic SOIC (S24)
Product Description
Pericom Semiconductors PI5C series of logic circuits are produced using the Companys advanced submicron CMOS technology, achieving industry performance. The PI5C3384A is a 10-bit, 2-port bus switches designed with a low ON resistance allowing inputs to be connected directly to outputs. The bus switch creates no additional propagational delay or additional ground bounce noise. The switches are turned ON by the Bus Enable (BE) input signal. Two bus enable signals are provided, one for each of the upper and lower five bits of the two 10-bit buses.

Notes: 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at Vcc = 5.0V, TA = 25C ambient and maximum loading. 3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second. 4. Measured by the voltage drop between A and B pin at indicated current through the switch. ON resistance is determined by the lower of the voltages on the two (A,B) pins. 5. This parameter is determined by device characterization but is not production tested.

Notes: 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device. 2. Typical values are at Vcc = 5.0V, +25C ambient. 3. Per TTL driven input (VIN = 3.4V, control inputs only); A and B pins do not contribute to Icc. 4. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified frequency. The A and B inputs generate no significant AC or DC currents as they transition. This parameter is not tested, but is guaranteed by design.

PI5C3384A Parameters Description tPLH tPHL tPZH tPZL tPHZ tPLZ Propagation Delay(2,3) Ax to Bx, Bx to Ax Bus Enable Time BEX to Ax or Bx Bus Disable Time BEx to Ax or Bx Conditions(1) CL = 50pF RL = 500 Min. -- 1.5 1.5 Max. 0.25 6.5 5.5 ns Units
Notes: 1. See test circuit and waveforms. 2. This parameter is guaranteed but not tested on Propagation Delays. 3. The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side.
