general description the max3372e?ax3379e and max3390e?ax3393e ?5kv esd-protected level translators provide the level shifting necessary to allow data transfer in a multivoltage system. externally applied voltages, v cc and v l , set the logic levels on either side of the device. a low-voltage logic signal present on the v l side of the device appears as a high-voltage logic signal on the v cc side of the device, and vice-versa. the max3374e/max3375e/ max3376e/max3379e and max3390e?ax3393e unidi- rectional level translators level shift data in one direction (v l v cc or v cc v l ) on any single data line. the max3372e/max3373e and max3377e/max3378e bidi- rectional level translators utilize a transmission-gate- based design (figure 2) to allow data translation in either direction (v l ? v cc ) on any single data line. the max3372e?ax3379e and max3390e?ax3393e accept v l from +1.2v to +5.5v and v cc from +1.65v to +5.5v, making them ideal for data transfer between low- voltage asics/plds and higher voltage systems. all devices in the max3372e?ax3379e, max3390e max3393e family feature a three-state output mode that reduces supply current to less than 1?, thermal short- circuit protection, and ?5kv esd protection on the v cc side for greater protection in applications that route sig- nals externally. the max3372e/max3377e operate at a guaranteed data rate of 230kbps. slew-rate limiting reduces emi emissions in all 230kbps devices. the max3373e?ax3376e/max3378e/max3379e and max3390e?ax3393e operate at a guaranteed data rate of 8mbps over the entire specified operating voltage range. within specific voltage domains, higher data rates are possible. (see timing characteristics .) the max3372e?ax3376e are dual level shifters available in 3 x 3 ucsp and 8-pin sot23-8 pack- ages. the max3377e/max3378e/max3379e and max3390e?ax3393e are quad level shifters avail- able in 3 x 4 ucsp and 14-pin tssop packages. ________________________applications spi , microwire , and i 2 c level translation low-voltage asic level translation smart card readers cell-phone cradles portable pos systems portable communication devices low-cost serial interfaces cell phones gps telecommunications equipment features guaranteed data rate options 230kbps 8mbps (+1.2v v l v cc +5.5v) 10mbps (+1.2v v l v cc +3.3v) 16mbps (+1.8v v l v cc +2.5v and +2.5v v l v cc +3.3v) bidirectional level translation (max3372e/max3373e and max3377e/max3378e) operation down to +1.2v on v l ?5kv esd protection on i/o v cc lines ultra-low 1? supply current in three-state output mode low-quiescent current (130? typ) ucsp, sot, and tssop packages thermal short-circuit protection max3372e?ax3379e/max3390e?ax3393e ?5kv esd-protected, 1?, 16mbps, dual/quad low-voltage level translators in ucsp ________________________________________________________________ maxim integrated products 1 three-state i/o v l 1 i/o v l 2 1 2 8 7 i/o v cc 1 v cc gnd v l i/o v cc 2 sot23-8 top view 3 4 6 5 max3372e/ max3373e pin configurations 19-2328; rev 3; 9/03 for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. ordering information ucsp is a trademark of maxim integrated products, inc. spi is a trademark of motorola, inc. i 2 c is a trademark of phillips corp. microwire is a trademark of national semiconductor corp. ordering information continued at end of data sheet. selector guide appears at end of data sheet. pin configurations continued at end of data sheet. part number temp range pin- package max3372e eka-t -40 c to +85 c 8 sot23-8

(see timing characteristics .) level translation for proper operation ensure that +1.65v v cc +5.5v, +1.2v v l +5.5v, and v l (v cc + 0.3v). during power-up sequencing, v l (v cc + 0.3v) will not damage the device. during power-supply sequencing, when v cc is floating and v l is powering up, a current may be sourced, yet the device will not latch up. the speed-up max3372e?ax3379e and

in ucsp ______________________________________________________________________________________ 11 circuitry limits the maximum data rate for devices in the max3372e max3379e, max3390e max3393e family to 16mbps. the maximum data rate also depends heavily on the load capacitance (see typical operating characteristics ), output impedance of the driver, and the operational voltage range (see timing characteristics). speed-up circuitry the max3373e max3376e/max3378e/max3379e and max3390e max3393e feature a one-shot generator that decreases the rise time of the output. when triggered, mosfets pu1 and pu2 turn on for a short time to pull up i/o v l_ and i/o v cc_ to their respective supplies (see figure 2b). this greatly reduces the rise time and propa- gation delay for the low-to-high transition. the scope photo of rail-to-rail driving for 8mbps operation in the typical operating characteristics shows the speed-up circuitry in operation. three-state output mode pull three-state low to place the max3372e max3379e and max3390e max3393e in three-state out- put mode. connect three-state to v l (logic high) for normal operation. activating the three-state output mode disconnects the internal 10k ? pullup resistors on the i/o v cc and i/o v l lines. this forces the i/o lines to a high- impedance state, and decreases the supply current to less than 1a. the high-impedance i/o lines in three- state output mode allow for use in a multidrop network. when in three-state output mode, do not allow the voltage at i/o v l_ to exceed (v l + 0.3v), or the voltage at i/o v cc_ to exceed (v cc + 0.3v). thermal short-circuit protection thermal overload detection protects the max3372e max3379e and max3390e max3393e from short-circuit fault conditions. in the event of a short-circuit fault, when the junction temperature (t j ) reaches +152 c, a thermal sensor signals the three-state output mode logic to force the device into three-state output mode. when t j has cooled to +142 c, normal operation resumes. max3372e max3379e and max3390e max3393e i/o v l_ i/o v cc_ v cc v cc v l v l gnd i/o v cc_ t pd-vcc-lh t pd-vcc-hl i/o v l_ t rvcc t fvcc data r load c load figure 1c. open-drain

structures are incorporated on all pins to protect against electrostatic discharges encountered during handling and assembly. the i/o v cc lines have extra protection against static electricity. maxim s engineers have developed state-of- the-art structures to protect these pins against esd of 15kv without damage. the esd structures withstand high esd in all states: normal operation, three-state out- put mode, and powered down. after an esd event, maxim s e versions keep working without latchup, whereas competing products can latch and must be powered down to remove latchup. esd protection can be tested in various ways. the i/o v cc lines of this product family are characterized for protection to the following limits: 1) 15kv using the human body model 2) 8kv using the contact discharge method specified in iec 1000-4-2 3) 10kv using iec 1000-4-2 s air-gap discharge method esd test conditions esd performance depends on a variety of conditions. contact maxim for a reliability report that documents test setup, test methodology, and test results. human body model figure 3a shows the human body model and figure 3b shows the current waveform it generates when dis- charged into a low impedance. this model consists of a 100pf capacitor charged to the esd voltage of inter- est, which is then discharged into the test device through a 1.5k ? resistor. iec 1000-4-2 the iec 1000-4-2 standard covers esd testing and performance of finished equipment; it does not specifi- cally refer to integrated circuits. the max3372e max3379e and max3390e max3393e help to design equipment that meets level 3 of iec 1000-4-2, without the need for additional esd-protection components. the major difference between tests done using the human body model and iec 1000-4-2 is higher peak cur- rent in iec 1000-4-2, because series resistance is lower in the iec 1000-4-2 model. hence, the esd withstand voltage measured to iec 1000-4-2 is generally lower than that measured using the human body model. figure 4a shows the iec 1000-4-2 model, and figure 4b shows the current waveform for the 8kv, iec 1000-4-2, level 4, esd contact-discharge test. the air-gap test involves approaching the device with a charged probe. the contact-discharge method connects the probe to the device before the probe is energized. machine model the machine model for esd tests all pins using a 200pf storage capacitor and zero discharge resis- tance. its objective is to emulate the stress caused by contact that occurs with handling and assembly during manufacturing. of course, all pins require this protec- tion during manufacturing, not just inputs and outputs. therefore, after pc board assembly, the machine model is less relevant to i/o ports. charge-current- limit resistor discharge resistance
