DESCRIPTION

The DG441/442 monolithic quad analog switches are

designed to provide high speed, low error switching of

analog and audio signals. The DG441 has a normally closed

function. The DG442 has a normally open function.

Combining low on-resistance (50

Ω, typ.) with high speed

upgrading DG201A/202 sockets. Charge injection has been

minimized on the drain for use in sample-and-hold circuits.

To achieve high voltage ratings and superior switching

performance, the DG441/442 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.
