DESCRIPTION

The DG444B, DG445B are monolithic quad analog switches

designed to provide high speed, low error switching of

analog and audio signals. The DG444B, DG445B are

upgrades to the original DG444, DG445.

Combing low on-resistance (45 ?, typ.) with high speed

(tON 120 ns, typ.), the DG444B, DG445B are ideally suited

for Data Acquisition, Communication Systems, Automatic

Test Equipment, or Medical Instrumentation. Charge

injection has been minimized on the drain for use in

sample-and-hold circuits.

The DG444B, DG445B are built using Vishay Siliconix’s

high-voltage silicon-gate process. An epitaxial layer prevents

latchup.

When on, each switch conducts equally well in both

directions and blocks input voltages to the supply levels

when off.
