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 high-
voltage silicon gate CMOS process, resulting in lower on-
resistance, 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.
For additional information, please refer to Application Note
AN208 (FaxBack document #70606).
