general description maxim? max312/max313/max314 analog switches feature low on-resistance (10 max) and 1.5 on-resis- tance matching between channels. these switches con- duct equally well in either direction. they offer low leakage over temperature (2.5na at +85?). low power consumption and esd tolerance greater than 2000v per method 3015.7 are guaranteed. the max312/max313/max314 are quad, single- pole/single-throw (spst) analog switches. the max312 is normally closed (nc), and the max313 is normally open (no). the max314 has two nc switches and two no switches. all three devices operate from a single supply of +4.5v to +30v or from dual supplies of ?.5v to ?0v. ________________________applications test equipment communication systems pbx, pabx systems audio signal routing avionics sample-and-hold circuits data acquisition systems ____________________________features ? ? pin compatible with dg411/dg412/dg413 ? ? low on-resistance (6.5 typical) ? ? guaranteed r on match between channels (1.5 max) ? ? guaranteed r on flatness over specified signal range (2 max) ? ? guaranteed esd protection > 2000v per method 3015.7 ? ? crosstalk > 96db at 20khz ? ? single-supply operation: +4.5v to +30v dual-supply operation: 4.5v to 20v ? ? rail-to-rail signal handling max312/max313/max314 10 , quad, spst, cmos analog switches ________________________________________________________________ maxim integrated products 1 switches shown for logic "0" input max313 logic switch 0 1 off on top view dip/so/tssop so/max312 logic switch 0 1 on off max314 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 max314 vl 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 nc2 v+ v- nc1 com1 in1 max312 vl nc3 com3 in3 in4 com4 nc4 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 max313 vl no3 com3 in3 in4 com4 no4 gnd dip/so/tssop dip/so/tssop _____________________pin configurations/functional diagrams/truth tables part max312 cpe max312cse max312c/d 0? to +70? 0? to +70? 0? to +70? temp range pin-package 16 plastic dip 16 narrow so dice* 19-0420; rev 2; 7/02 ______________ordering information ordering information continued at end of data sheet. * contact factory for dice specifications. **contact factory for availability. max312epe max312ese -40? to +85? -40? to +85? 16 plastic dip 16 narrow so max312mje -55? to +125? 16 cerdip** max312cue 0? to +70? 16 tssop max312eue -40? to +85? 16 tssop 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. rail-to-rail is a registered trademark of nippon motorola ltd.

__________applications information low-distortion audio the max312/max313/max314, having very low r on and very low r on variation with signal amplitude, are well suited for low-distortion audio applications. the typical operating characteristics show total harmonic distortion (thd) vs. frequency graphs for several sig- nal amplitudes and impedances. higher source and load impedances improve thd, but reduce off isolation. off isolation at high frequencies in 50 systems, the high-frequency on-response of these parts extends from dc to above 100mhz with a typical loss of -2db. when the switch is turned off, how- ever, it behaves like a capacitor, and off isolation decreases with increasing frequency. (above 300mhz, the switch actually passes more signal turned off than turned on.) this effect is more pronounced with higher source and load impedances. above 5mhz, circuit board layout becomes critical, and it becomes difficult to characterize the response of the switch independent of the circuit. the graphs shown in the typical operating characteristics were taken using a 50 source and load connected with bnc connec- tors to a circuit board deemed ?verage? that is, designed with isolation in mind, but not using strip-line or other special rf circuit techniques. for critical appli- cations above 5mhz, use the max440, max441, and max442, which are fully characterized up to 160mhz. max312/max313/max314 10 , quad, spst, cmos analog switches _______________________________________________________________________________________ 7 v+ com_ v- no_ v g v+ v- t r < 20ns t f < 20ns 50% 0v logic input v- -15v r l 300 no1 or nc1 gnd c l includes fixture and stray capacitance. v o = v com ( r l ) r l + r on switch input in1 +3v t off 0v com1 switch output 0.9v 0 0.9v 0 t on v o switch output logic input logic input waveforms inverted for switches that have the opposite logic sense. vl v+ c l 35pf +5v +15v v o v com1 0v repeat test for each switch. for load conditions, see electrical characteristics. max312 max313 max314 figure 1. overvoltage protection using external blocking diodes figure 2. switching-time test circuit
