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 V
connects to ANO_.
