Audio Input 1. Normally open terminal for switch 1.

Ground

Positive Supply-Voltage Input. Bypass VCC to GND with a 0.1µF capacitor as

close to the device as possible.

Common Terminal for Switch 1

Common Terminal for Switch 2

Digital Control Input. Drive CB low to connect COM_ to UNC_. Drive CB high to

connect COM_ to ANO_.

Active-High Enable Input. Drive EN high for normal operation. Drive EN low to put

switches in high impedance. Do not connect negative signals to ANO_ or

COM_ when EN is low.

USB Input 2. Normally closed terminal for switch 2.

Audio Override Input. Drive AOR low to have VB control the switch. Drive AOR

high to connect COM_ to ANO_. AOR has an internal pulldown resistor to GND.

VBUS Detection Input. If VVB ≥ VVBDET, COM_ connects to UNC_.

Otherwise, COM_ connects to ANO_.
