________________general description the max4524/max4525 are low-voltage, single-supplycmos analog switches configured as a 4-channel mul- tiplexer/demultiplexer (max4524) and a double- pole/double-throw (dpdt) switch (max4525). both have an inhibit input to simultaneously open all signal paths. these devices operate from a single supply of +2v to +12v and are optimized for operation with +3v or +5v supplies. on-resistance is 200 with a +5v supply and 500 with a +3v supply. each switch can handle rail- to-rail analog signals. the off-leakage current is only2na at +25? or 20na at +85?. all digital inputs have 0.8v to 2.4v logic thresholds, ensuring ttl/cmos-logic compatibility when using a single +5v supply. ________________________applications battery-operated equipmentaudio and video signal routing low-voltage data-acquisition systems communications circuits ____________________________features ? tiny 10-pin tdfn package ? single-supply operation from +2v to +12v ? 200 on-resistance with +5v supply ? 500 on-resistance with +3v supply ? guaranteed 8 on-resistance match at +5v ? guaranteed 2na max on-leakage at +5v ? ttl/cmos-logic compatible max4524/max4525 low-voltage, single-supply multiplexer and switch ________________________________________________________________ maxim integrated products 1 1 23 4 5 10 98 7 6 v+com no0 adda inh no1 no3 no2 max4524 max top view addb gnd inh 10 0 0 0 inh 1 max4525max4524 add x 0001 on switch none coma-nca, comb-ncb coma-noa, comb-nob addb x 00 1 1 x = don? care adda x 01 0 1 on switch none com-no0com-no1 com-no2 com-no3 logic 1 23 4 5 10 98 7 6 v+comb nob ncb inh nca coma noa max4525 max add gnd logic 1 23 4 5 10 98 7 6 v+com no0 adda inh no1 no3 no2 tdfn addb gnd logic 1 23 4 5 10 98 7 6 v+comb nob ncb inh nca coma noa tdfn add gnd logic ______________________pin configurations/functional diagrams/truth tables 19-1332; rev 2; 6/07 _______________ordering information * contact factory for availability. ** ep = exposed pad. part temp range pin-package top mark max4524 cub 0 c to +70 c 10 ?ax max4524c/d 0 c to +70 c dice* max4524eub -40 c to +85 c 10 ?ax max4524etb -40 c to +85 c 10 tdfn-ep**(3mm x 3mm) aap max4525 cub 0 c to +70 c 10 ?ax max4525c/d 0 c to +70 c dice* max4525eub -40 c to +85 c 10 ?ax max4525etb -40 c to +85 c 10 tdfn-ep**(3mm x 3mm) aaq 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. downloaded from: http:///

__________applications information power-supply considerations the max4524/max4525 s construction is typical of most cmos analog switches. they have two supplypins: v+ and gnd. v+ and gnd are used to drive the internal cmos switches and set the limits of the analog voltage on any switch. reverse esd-protection diodes are internally connected between each analog signal pin and both v+ and gnd. if any analog signal exceeds v+ or gnd, one of these diodes will conduct. during normal operation, these (and other) reverse- biased esd diodes leak, forming the only current drawn from v+ or gnd. virtually all the analog leakage current comes from theesd diodes. although the esd diodes on a given sig- nal pin are identical, and therefore fairly well balanced, they are reverse-biased differently. each is biased by either v+ or gnd and the analog signal. this means that leakage will vary as the signal varies. the differ- ence in the two diode leakages to the v+ and gnd pins constitutes the analog signal-path leakage current. all analog leakage current flows between each pin and one of the supply terminals, not to the other switch ter- minal. this is why both sides of a given switch can show leakage currents of either the same or opposite polarity. max4524/max4525 low-voltage, single-supply multiplexer and switch _______________________________________________________________________________________ 7 ______________________________________________test circuits/timing diagrams 50% t trans v+ 0v v no0 v out v add 0v 90% 90% t trans 50% t trans v+ 0v v nc v out v add 0v 90% 90% t trans v add v+ v out gnd v+ addb adda inh no0 no1?o2 no3 com v+ max4524 300 50 35pf v+ v out gnd v+ add v add inh no nc com v+ max4525 300 50 35pf repeat test for each section. figure 1. address transition time downloaded from: http:///
max4524/max4525 there is no connection between the analog signalpaths and gnd. v+ and gnd power the internal logic and logic-level translators, and set both the input and output logic limits. the logic-level translators convert the logic levels into switched v+ and gnd signals to drive the gates of the analog signals. this drive signal is the only connection between the logic supplies (and signals) and the analog supplies. v+ has an esd-pro- tection diode to gnd. low-voltage operation these devices operate from a single supply between+2v and +12v. at room temperature, they actually work with a single supply at near or below +1.7v, although as supply voltage decreases, switch on-resis-tance and switching times become very high. high-frequency performance in 50 systems, signal response is reasonably flat up to 50mhz (see typical operating characteristics ). above 20mhz, the on-response has several minorpeaks, which are highly layout dependent. the problem is not turning the switch on, but turning it off. the off- state switch acts like a capacitor, and passes higher frequencies with less attenuation. at 10mhz, off-isola- tion is about -50db in 50 systems, becoming worse (approximately 20db per decade) as frequencyincreases. higher circuit impedances also degrade off- isolation. adjacent channel attenuation is about 3db above that of a bare ic socket, and is entirely due to capacitive coupling. low-voltage, single-supply multiplexer and switch 8 _______________________________________________________________________________________ _________________________________test circuits/timing diagrams (continued) 50% t off v+ 0v v no0 v out v inh 0v 90% 90% t on 50% t off v+ 0v v no_ v out v inh 0v 90% 90% t on v inh v inh v+ v out gnd v+ addb adda inh no0 no1?o3 com v+ max4524 300 50 35pf v+ v out gnd v+ add inh no_ nc_ com_ v+ max4525 300 35pf 50 repeat test for each section. figure 2. inhibit switching times downloaded from: http:///
