general description maxim? max312l/max313l/max314l analog switch- es feature low on-resistance (10 ? max) and 1.5 ? on- resistance matching between channels. these switches are +3v logic compatible when powered from ?5v or +12v supplies. the switches conduct equally well in either direction, and offer low leakage over temperature (2.5na at +85?). the max312l/max313l/max314l are quad, single- pole/single-throw (spst) analog switches. the max312l is normally closed (nc), and the max313l is normally open (no). the max314l has two nc switches and two no switches. all three devices operate from a single +4.5v to +36v supply or from dual ?.5v to ?0v, and are available in 16-pin tssop, so, and dip packages. applications test equipment communication systems pbx, pabx systems audio signal routing avionics sample-and-hold circuits data-acquisition systems xdsl modems features +3v logic-compatible digital inputs v ih = 2.0v v il = 0.8v pin compatible with max312/max313/max314 and dg411/dg412/dg413 low on-resistance (10 ? max) guaranteed r on match between channels (1.5 ? max) guaranteed r on flatness over specified signal range (2 ? max) crosstalk > 96db at 20khz single-supply operation: +4.5v to +36v dual-supply operation: ?.5v to ?0v rail-to-rail signal handling max312l/max313l/max314l 10 ? , quad, spst, +3v logic-compatible analog switches ________________________________________________________________ maxim integrated products 1 ordering information 19-2184; rev 0; 10/01 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. ordering information continued at end of data sheet. pin configurations 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 in3 com3 nc3 n.c. v+ nc2 com2 in2 top view max312l in4 com4 nc4 gnd v- nc1 com1 in1 max312l logic 0 1 switch on off dip/so/tssop 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 in3 com3 no3 n.c. v+ no2 com2 in2 max313l in4 com4 no4 gnd v- no1 com1 in1 switches shown for logic "0" input max313l logic 0 1 switch off on dip/so/tssop 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 in3 com3 nc3 n.c. v+ nc2 com2 in2 max314l in4 com4 no4 gnd v- no1 com1 in1 max314l switches 1, 4 logic switches 2, 3 0 1 on off off on dip/so/tssop part temp. range pin-package max312l cue 0 c to +70 c 16 tssop MAX312LCSE 0 c to +70 c 16 narrow so max312lcpe 0 c to +70 c 16 plastic dip max312leue -40 c to +85 c 16 tssop max312lese -40 c to +85 c 16 narrow so max312lepe -40 c to +85 c 16 plastic dip

applications information low-distortion audio the max312l/max313l/max314l, 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 signal 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 connectors. power-supply sequencing-free operation most cmos switches require specific power-supply sequencing in order to prevent the devices from latching up. the older max312/max313/max314 devices require a proper power-supply sequence of v+, v l , v-, and so forth. otherwise, it becomes necessary to add signal diodes to the circuit in order to protect it from potential latchups. the new max312l/max313l/ max314l devices eliminate the need for a v l pin and permit the user to utilize any power-up sequence that is required. it is, however, important not to exceed the absolute maxi- mum ratings because stresses beyond the listed ratings may cause permanent damage to the devices. chip information transistor count: 92 process: cmos max312l/max313l/max314l 10 ? , quad, spst, +3v logic-compatible analog switches _______________________________________________________________________________________ 7 pin description pin max312l max313l max314l name function 1, 8, 9, 16 1, 8, 9, 16 1, 8, 9, 16 in1, in4, in3, in2 logic inputs 2, 7, 10, 15 2, 7, 10, 15 2, 7, 10, 15 com1, com4, com3, com2 analog signal common terminals 3, 6, 11, 14 nc1, nc4, nc3, nc2 analog signal normally closed terminals 3, 6, 11, 14 no1, no4, no3, no2 analog signal normally open terminals 3, 6 no1, no4 analog signal normally open terminals 11, 14 nc3, nc2 analog signal normally closed terminals 444 v- negative analog supply input (connect to gnd for single- supply operation) 5 5 5 gnd ground 12 12 12 n.c. no connection. not internally connected. 13 13 13 v+ positive analog supply input
