general description the dg201a and dg211 are normally closed, quadsingle-pole single-throw (spst) analog switches. these cmos switches can be continuously operated with power supplies ranging from ?.5v to ?8v. maxim guarantees that these switches will not latch up if the power supplies are disconnected with input signals still connected. both devices have guaranteed break-before-make switching. the dg201a differs from the dg211 primari- ly in switching speeds. the dg201a has a maximum turn-off time of 450ns and a maximum turn-on time of 600ns. the dg211 has a maximum turn-off time of 500ns and a maximum turn-on time of 1000ns. compared to the original manufacturer? products, maxim? dg201a and dg211 consume significantly lower power making them better suited for portable applications. maxim has also eliminated the need for the third (v l ) power supply that is required for the oper- ation of the original manufacturer? dg211. applications winchester disk drivestest equipment communications systems pbx, pabx guidance and control systems head up displays military radios features ? guaranteed ?.5v to ?8v operation ? no v l supply required ? nonlatching with supplies turned off and inputsignals present ? cmos and ttl logic compatible ? monolithic, low-power cmos design dg201a/dg211 quad spst cmos analog switches ________________________________________________________________ maxim integrated products 1 top view dip/so/tssop logic switch 01 on off 1615 14 13 12 11 10 9 12 3 4 5 6 7 8 in2d2 s2 v+ v- s1 d1 in1 dg201a dg211 n.c.s3 d3 in3 in4 d4 s4 gnd pin configurations ordering information 19-3959; rev 2; 5/06 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. part temp range pin-package dg201a cue 0 c to +70 c 16 tssop dg201acse 0 c to +70 c 16 so dg201acj 0 c to +70 c 16 plastic dip dg201c/d 0 c to +70 c dice dg201aege -40 c to +85 c 16 qfn (5 ? 5) dg201aeue -40 c to +85 c 16 tssop dg201ady -40 c to +85 c 16 so dg201adj -40 c to +85 c 16 plastic dip dg201aak -55 c to +125 c 16 cerdip dg201abk -25 c to +85 c 16 cerdip dg211 cue 0 c to +70 c 16 tssop dg211cse 0 c to +70 c 16 so dg211cj 0 c to +70 c 16 plastic dip dg211c/d 0 c to +70 c dice dg211ege -40 c to +85 c 16 qfn (5 ? 5) dg211eue -40 c to +85 c 16 tssop dg211dy -40 c to +85 c 16 so DG211DJ -40 c to +85 c 16 plastic dip 1615 14 13 12 11 10 9 12 34 5 6 7 8 +15v dg201a dg211 -15v v in x 10v * * * * 5k 10k 40k 20k 5k v out programmable gain amplifier note: *pins 1, 8, 9, and 16 are logic control inputs t ypical operating circuit pin configurations continued at end of data sheet. downloaded from: http:///
