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
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.
