DG221B Overview
The DG221B is a monolithic quad single-pole, single-throw analog switch designed for precision switching applications in munication, instrumentation and process control systems. Featuring independent onboard latches and a mon WR pin, each DG221B can be memory mapped, and addressed as a single data byte for simultaneous switching. The DG221B bines low power and low on-resistance (60 typical) while handling continuous...
