general description the MAX4521/max4522/max4523 are quad, low-volt- age, single-pole/single-throw (spst) analog switches. on-resistance (100 ? max) is matched between switch- es to 4 ? max, and is flat (12 ? max) over the specified signal range. each switch can handle rail-to-rail ana- log signals. the off-leakage current is only 1na at +25? and 10na at +85?. the MAX4521 has four normally closed (nc) switches, and the max4522 has four normally open (no) switch- es. the max4523 has two nc switches and two no switches. these cmos switches can operate with dual power supplies ranging from ?v to ?v or a single supply between +2v and +12v. they are fully specified for sin- gle +2.7v operation. all digital inputs have +0.8v and +2.4v logic thresh- olds, ensuring ttl/cmos-logic compatibility when using ?v or a single +5v supply. applications battery-operated equipment data acquisition test equipment avionics audio signal routing networking features +2v to +12v single supply ?v to ?v dual supplies 100 ? signal paths with ?v supplies low power consumption, <1? 4 separately controlled spst switches rail-to-rail signal handling pin compatible with industry-standard dg211/dg212/dg213 >2kv esd protection per method 3015.7 ttl/cmos-compatible inputs with ?v or single +5v supply MAX4521/max4522/max4523 quad, low-voltage, spst analog switches ________________________________________________________________ maxim integrated products 1 switches shown for logic "0" input dip/so/qsop/tssop max4522 logic switch 0 1 off on top view dip/so/qsop/tssop MAX4521 logic switch 0 1 on off dip/so/qsop/tssop max4523 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 max4523 n.c. 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 MAX4521 n.c. 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 max4522 n.c. no3 com3 in3 in4 com4 no4 gnd n.c. = not connected pin configurations/functional diagrams/truth tables 19-1136; rev 3; 10/01 part MAX4521 cpe MAX4521cse MAX4521cee 0? to +70? 0? to +70? 0? to +70? temp. range pin-package 16 plastic dip 16 narrow so 16 qsop ordering information ordering information continued at end of data sheet. * contact factory for dice specifications.

MAX4521/max4522/max4523 applications information power-supply considerations overview the MAX4521/max4522/max4523 construction is typi- cal of most cmos analog switches. they have three supply pins: v+, v-, and gnd. v+ and v- are used to drive the internal cmos switches, and they set the lim- its of the analog voltage on any switch. reverse esd- protection diodes are internally connected between each analog-signal pin and both v+ and v-. if any ana- log signal exceeds v+ or v-, one of these diodes con- ducts. during normal operation these reverse-biased esd diodes leak, forming the only current drawn from v+ or v-. virtually all the analog leakage current is through the esd 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 v- and the analog signal. this means their leakages vary as the signal varies. the difference in the two diode leakages from the signal path to the v+ and v- pins constitutes the analog-signal-path leakage cur- rent. all analog leakage current flows to the supply ter- minals, not to the other switch terminal. this explains how 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 gnd. the analog-signal paths consist of an n-channel and p-channel mosfet with their sources and drains paralleled, and their gates driven out of phase to v+ and v- by the logic-level translators. v+ and gnd power the internal logic and logic-level translators, and set the input logic thresholds. the logic-level translators convert the logic levels to switched v+ and v- signals to drive the gates of the analog switches. this drive signal is the only connec- tion between the logic supplies and the analog sup- plies. v+ and v- have esd-protection diodes to gnd. the logic-level inputs and output have esd protection to v+ and to gnd. increasing v- has no effect on the logic-level thresh- olds, but it does increase the drive to the p-channel switches, reducing their on-resistance. v- also sets the negative limit of the analog-signal voltage. the logic-level thresholds are cmos/ttl compatible when v+ = +5v. the threshold increases slightly as v+ is raised, and when v+ reaches +12v, the level thresh- old is about 3.1v. this is above the ttl output high- level minimum of 2.8v, but still compatible with cmos outputs. bipolar supplies the MAX4521/max4522/max4523 operate with bipolar supplies between 2v and 6v. the v+ and v- sup- plies need not be symmetrical, but their sum cannot exceed the absolute maximum rating of 13.0v. do not connect the MAX4521/max4522/max4523 v+ to +3v, and then connect the logic-level-input pins to ttl logic-level signals. ttl logic-level outputs in excess of the absolute maximum ratings can damage the part and/or external circuits. caution: the absolute maximum v+ to v- differential voltage is 13.0v. typical 6v or 12v supplies with 10% tolerances can be as high as 13.2v. this voltage can damage the MAX4521/max4522/max4523. even 5% tolerance supplies may have overshoot or noise spikes that exceed 13.0v. single supply the MAX4521/max4522/max4523 operate from a single supply between +2v and +12v when v- is con- nected to gnd. all of the bipolar precautions must be observed. 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 minor peaks that are highly layout dependent. the problem with high-frequency operation 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-isolation is about -52db in 50 ? systems, becoming worse (approximately 20db per decade) as frequency increases. higher circuit impedances also make off-isolation worse. adjacent channel attenuation is about 3db above that of a bare ic socket, and is due entirely to capacitive coupling. quad, low-voltage, spst analog switches 8 _______________________________________________________________________________________
