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.
