ISL54402 Operation
The ISL54402 is an audio/data switch. Its logic control is
typical of a standard dual SPDT switch.
The digital control for the ISL54402 are the IN pins (pin 2
and pin 10). These pins are 1.8V logic compatible when
operated with a 3.0V supply. The device has been designed
to have low I
the rail. With V
draws only 8µA current.

When logic pin IN1 (pin 10) is LOW the NC1 audio switch is
ON and the NO1 USB data switch is OFF. When logic pin
IN1 (pin 10) is HIGH the NC1 audio switch is OFF and the
NO1 USB data switch is ON.
When logic pin IN2 (pin 2) is LOW the NC2 audio switch is
ON and the NO2 USB data switch is OFF. When logic pin
IN2 (pin 2) is HIGH the NC2 audio switch is OFF and the
NO2 USB data switch is ON.
Power for the ISL54402 device is always provided by the DC
voltage source connected at the V
power supply voltage range is from 1.8V to 5.5V.
