_______________general description the max4514/max4515 are single-pole/single-throw(spst), cmos, low-voltage, single-supply analog switches with very low switch on-resistance. the max4514 is normally open (no). the max4515 is nor- mally closed (nc). these cmos switches can operate continuously with a single supply between +2v and +12v. each switch can handle rail-to-rail analog signals. the off-leakage cur- rent maximum is only 1na 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 +5v supply. for pin-compatible parts for use with dual supplies, see the max4516/max4517. ________________________applications battery-operated equipmentaudio and video signal routing low-voltage data-acquisition systems communications circuits pcmcia cards cellular phones modems ____________________________features ? available in sot23-5 package ? +2v to +12v single-supply operation ? guaranteed on-resistance: 20 with +5v supply 10 with +12v supply ? guaranteed low off-leakage currents: 1na at +25?20na at +85? ? guaranteed low on-leakage currents: 2na at +25?40na at +85? ? low charge injection: 10pc ? fast switching speed: t on = 150ns, t off = 100ns ? break-before-make operation: t on > t off at +5v ? ttl/cmos-logic compatible with +5v supply max4514/max4515 low-voltage, low-on-resistance, spst, cmos analog switches ________________________________________________________________ maxim integrated products 1 top view in n.c. n.c. v+ 12 8 7 nognd n.c. com max4514 dip/so 34 65 in n.c. n.c. v+ 12 8 7 ncgnd n.c. com max4515 dip/so 34 65 n.c. = not internally connected no in gnd 1 5 v+ com max4514 sot23-5 23 4 nc in gnd 1 5 v+ com max4515 sot23-5 23 4 input low high switch state max4514 off on max4515 on off marking information (sots only) ae = max4514af = max4515 lot specific code xx xx __________________________________________________________pin configurations 19-1069; rev 1; 5/05 part max4514 cpa max4514csa max4514cuk 0? to +70? 0? to +70? 0? to +70? temp range pin-package 8 plastic dip8 so 5 sot23-5 ______________ordering information ordering information continued at end of data sheet. * contact factory for dice specifications. max4514c/d 0? to +70? dice* 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:///

max4514/max4515 low-voltage, low-on-resistance, spst, cmos analog switches 6 _______________________________________________________________________________________ __________applications information power-supply considerations the max4514/max4515 construction is typical of mostcmos analog switches, except that they have only two supply pins: v+ and gnd. v+ and gnd drive the inter- nal cmos switches and set their analog voltage limits. reverse esd-protection diodes are internally connect- ed between each analog-signal pin and both v+ and gnd. one of these diodes conducts if any analog sig- nal exceeds v+ or gnd. virtually all the analog leakage current comes from the esd diodes to v+ or gnd. although the esd diodes on a given signal 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 their leakages will vary as the signal varies. the difference 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 termi- nal. this is why both sides of a given switch can show leakage currents of the same or opposite polarity. there is no connection between the analog-signal paths and v+ or gnd. v+ and gnd also power the internal logic and logic- level translators. the logic-level translators convert the logic levels to switched v+ and gnd signals to drive the analog signal gates. logic-level thresholds the logic-level thresholds are cmos/ttl compatiblewhen v+ is +5v. as v+ is raised, the level threshold increases slightly. when v+ reaches +12v, the level threshold is about 3.0v?bove the ttl guaranteed high-level minimum of 2.8v, but still compatible with cmos outputs. do not connect the max4514/max4515 s v+ to +3v and then connect the logic-level pins to logic-levelsignals that operate from +5v supply. output levels can exceed +3v and violate the absolute maximum ratings, damaging the part and/or external circuits. high-frequency performance in 50 systems, signal response is reasonably flat up to 250mhz (see typical operating characteristics ). above 20mhz, the on response has several minor peaks that are highly layout dependent. the problem is not in turn- ing the switch on; it? in turning it off. the off-state switch acts like a capacitor and passes higher frequencies with less attenuation. at 10mhz, off isolation is about -45db in 50 systems, decreasing (approximately 20db per decade) as frequency increases. higher circuit imped- ances also make off isolation decrease. off isolation is about 3db above that of a bare ic socket, and is due entirely to capacitive coupling. ? v out v+0v v in v out max4515 max4514 ? v out is the measured voltage due to charge transfer error q when the channel turns off.q = ? v out x c l v+ v out gnd v+ in no or nc com v no or v nc = 0v 50 max4514max4515 c l 1000pf v in figure 1. charge injection ______________________________________________test circuits/timing diagrams downloaded from: http:///
