DESCRIPTION

The DG221B 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 DG221B can be memory mapped, and addressed as

a single data byte for simultaneous switching.

The DG221B combines low power and low on-resistance (60

W typical) while handling continuous currents up to 20 mA. An

epitaxial layer prevents latchup.

The device features true bidirectional performance in the on

condition.
