Description

The DG201HS is an improved monolithic device

containing four independent analog switches. It is

designed to provide high speed, low error switching of

analog signals. Combining low on-resistance (25

W) with

high speed data acquisition requirements.

To achieve high voltage ratings and superior switching

performance, the DG201HS is built on a proprietary

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 values,

when off.
