1 G444, G44 Quad SPST MOS Analog Switches APPLIATIONS Audio switching Battery powered systems ata acquisition Sample-and-hold circuits Telecommunication systems Automatic test equipment Single supply circuits Hard disk drives ESRIPTION The G444, G44 monolithic quad analog switches are designed to provide high speed, low error switching of analog signals. The G444 has a normally closed function. The G44 has a normally open function. ombining low power (22 nw, typ) with high speed ( : 12 ns, typ.), the G444, G44 are ideally suited for upgrading G211, G212 sockets. harge injection has been minimized on the drain for use in sample-and-hold circuits. To achieve high-voltage ratings and superior switching performance, the G444, G44 are built on Vishay Siliconix s high-voltage silicon-gate process. An epitaxial layer prevents latchup. Each switch conducts equally well in both directions when on, and blocks input voltages to the supply levels when off. FEATURES Low on-resistance: Low leakage: 8 pa Low power consumption: 22 nw Fast switching action - : 12 ns Low charge injection G211, G212 upgrades TTL/MOS logic compatible BENEFITS Low signal errors and distortion Reduced power supply requirements Faster throughput Improved reliability Reduced pedestal errors Simple interfacing FUNTIONAL BLOK IAGRAM AN PIN ONFIGURATION ual-in-line and SOI IN IN S S 2 V G444 GN 12 V L S S IN IN 3 TRUTH TABLE Logic G444 G44 On Off 1 Off On Logic "".8 V Logic "1" 2.4 V ORERING INFORMATION Temp.
