Note: The switches are bidirectional, which means that a signal can be passed through either side of the on switch. However,
the typical off-capacitances differ as shown in the
Electrical Characteristics.
IN Logic-Controlled Input
V+ Positive Supply Voltage Input. Bypass with a 0.1μF capacitor to GND.
GND Ground
NO Analog-Switch Normally Open Terminal
COM Analog-Switch Common Terminal
NC Analog-Switch Normally Closed Terminal
N.C. No Connection. Not internally connected.
