Analog Switch Common Terminals

Logic-Controlled Inputs

Ground

Positive Supply Input. Bypass with a 0.1µF capacitor to GND.

Note: NO_, NC_, and COM_ pins are identical and interchangeable. Signals can be passed through either side of these bidirectional

switches. However, the typical off-capacitances differ, as shown in the Electrical Characteristics.
