DESCRIPTION

The DG444B/445B are monolithic quad analog switches

designed to provide high speed, low error switching of analog

and audio signals. The DG444B/445B are upgrades to the

original DG444/445.

been minimized on the drain for use in sample-and-hold

circuits.

The DG444B/445B are built using Vishay Siliconix’s

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

latchup.

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

120 ns, typ.), the DG444B/445B are ideally suited for Data

Acquisition, Communication Systems, Automatic Test

Equipment, or Medical Instrumentation. Charge injection has

When on, each switch conducts equally well in both directions

and blocks input voltages to the supply levels when off.
