general description maxim? dg300?g303 and dg300a?g303a cmosdual and quad analog switches combine low power operation with fast switching times and superior dc and ac switch characteristics. on-resistance is less than 50 and is essentially constant over the analog signal range. device specifications are ideal for battery-powered circuitry. these switches are available in a variety of formats as outlined in the pin configurations section. the switch control logic inputs are fully ttl and cmos compati- ble. also featured are ?reak-before-make?switching and low charge injection. maxim? dg300-dg303 and dg300a-dg303a families are electrically compatible and pin compatible with the original manufacturer? devices. all devices operate with power supplies ranging from ?v to ?8v. single-sup- ply operation is implemented by connecting v- to gnd. applications portable instrumentslow-power sample/holds power-supply switching programmable gain amplifiers spdt and dpdt functions process control and telemetry features ? monolithic low-power cmos ? latchup proof construction ? fully compatible 2nd source ? low on-resistance, <50 ? fast switching time ? v+ to v- analog signal range ? single-supply capability dg300(a)/dg301(a)/dg302(a)/dg303(a) ttl compatible cmos analog switches ________________________________________________________________ maxim integrated products 1 v+d 2 n.c.s 2 s 1 n.c. d 1 n.c. 1413 12 11 10 9 8 1 23 45 6 7 n.c. in 2 v- gnd in 1 n.c. 10 1 2 3 4 5 6 7 8 9 d 1 s 1 in 1 n.c. gnd 1 0 logic on off switch dual spst dg300/dg300a dual dpst dg302/dg302a v+ (substrate and case) v- in 2 s 2 d 2 v+s 4 d 4 d 2 d 1 d 3 s 3 n.c. s 2 in 2 v- gnd in 1 s 1 dual spdt dg303/dg303a v+s 4 d 4 d 2 d 1 d 3 s 3 n.c. s 2 in 2 v- gnd in 1 s 1 1 0 logic on off switch v+d 2 n.c.s 2 s 1 n.c. d 1 n.c. n.c. n.c. v- switch states are for logic "1" inputs (positive logic). gnd in n.c. 10 1 2 3 4 5 6 7 8 9 d 1 s 1 in n.c. gnd 1 0 logic on off switch 1 off on switch 2 spdt dg301/dg301a v+ (substrate and case) v- n.c. s 2 d 2 1 0 logic on off switches 1, 2 off on switches 3, 4 1413 12 11 10 9 8 1 23 45 6 7 1413 12 11 10 9 8 1 23 45 6 7 1413 12 11 10 9 8 1 23 45 6 7 pin configurations ordering information 19-0309; rev 3; 11/07 for pricing, delivery, and ordering information, please contact maxim direct at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. ordering information continued at end of data sheet. part temp range pin-package dg300 c/d 0? to +70? dice dg300cj 0? to +70? 14 lead plastic dip dg300cwe 0? to +70? 16 lead wide so dg300ck 0? to +70? 14 lead cerdip dg300bwe -25? to +85? 16 lead wide so dg300bk -25? to +85? 14 lead cerdip dg300ba -25? to +85? 10 lead metal can dg300ak -55? to +125? 14 lead cerdip dg300aa -55? to +125? 10 lead metal can downloaded from: http:///
