DESCRIPTION

The versatile DG213 analog switch has two NC and two NO

switches. It can be used in various configurations, including

four single-pole single-throw (SPST), two single-pole

double-throw (SPDT), one “T” switch, one DPDT, etc. This

device is fabricated in a Vishay Siliconix’ proprietary highvoltage

silicon gate CMOS process, resulting in lower onresistance,

lower leakage, higher speed, and lower power

consumption.

This analog switch was designed for a wide variety of

general purpose applications in telecommunications,

instrumentation, process control, computer peripherals, etc.

An improved charge injection compensation design

minimizes switching transients. These switches can handle

up to ± 22 V, and have an improved continuous current

rating of 30 mA. An epitaxial layer prevents latchup.

All switches feature true bi-directional performance in the on

condition, and will block signals to the supply levels in the off

condition.
