10 7 V+
Positive-Supply Voltage Input. Connect V+ to a 3.0V to 3.6V supply voltage. Bypass V+ to
GND with a 0.1µF capacitor.

SHDN
Shutdown Input. Drive SHDN high to put the device into shutdown mode. For normal
operation, drive SHDN low.
MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS AT IC TERMINALS.
OFF-ISOLATION IS MEASURED BETWEEN COM_ AND "OFF" NO_ OR NC_ TERMINAL ON EACH SWITCH.
ON-LOSS IS MEASURED BETWEEN COM_ AND "ON" NO_ OR NC_ TERMINAL ON EACH SWITCH.
CROSSTALK IS MEASURED FROM ONE CHANNEL TO THE OTHER CHANNEL.
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
