DG444, DG445 www.vishay.com Vishay Siliconix Quad SPST CMOS Analog Switches APPLICATIONS FEATURES Audio switching Low on-resistance: 50 Battery powered systems Low leakage: 80 pA Data acquisition Low power consumption: 22 nW Sample-and-hold circuits Fast switching action - t : 120 ns ON Telecommunication systems Low charge injection Automatic test equipment DG211, DG212 upgrades Single supply circuits TTL/CMOS logic compatible Hard disk drives BENEFITS DESCRIPTION Low signal errors and distortion The DG444, DG445 monolithic quad analog switches are Reduced power supply requirements designed to provide high speed, low error switching of Faster throughput analog signals. The DG444 has a normally closed function. Improved reliability The DG445 has a normally open function. Combining low Reduced pedestal errors power (22 nW, typ.) with high speed (t : 120 ns, typ.), the ON DG444, DG445 are ideally suited for upgrading DG211, Simple interfacing DG212 sockets. Charge injection has been minimized on the Wide supply ranges drain for use in sample-and-hold circuits. - Single supply: +5 V to 36 V To achieve high-voltage ratings and superior switching - Dual supplies: 5 V to 20 V performance, the DG444, DG445 are built on Vishay Siliconixs 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.
