Description

The DG221 is a monolithic quad single-pole, single-throw

analog switch designed for precision switching applications in

communication, instrumentation and process control systems.

Featuring independent onboard latches and a common WR

pin, each DG221 can be memory mapped, and addressed as

a single data byte for simultaneous switching.

Designed on the Siliconix PLUS-40 CMOS process, the

Functional Block Diagram and Pin Configuration

DG221 combines low power and low on-resistance (60

typical) while handling continuous currents up to 20 mA.

An epitaxial layer prevents latchup.

The device features true bidirectional performance in the on

condition. These switches guarantee a rail-to-rail blocking

capability (44 V max), in the off condition.
