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 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 t...
