DESCRIPTION
The TS3A26746E is a 2 × 2 cross-point switch that is used to interchange the Ground and MIC connections on a
headphone connector. The Ground switch has an ultra low R_ON of <0.1Ω to minimize voltage drop across it,
preventing undesired increases in headphone ground reference voltage. The switch state is controlled via the
SEL input. When SEL=High, GND is connected to RING2 and MIC is connected to SLEEVE. When SEL=Low,
GND is connected to SLEEVE and MIC is connected to RING2. An internal 100k pull-up resistor on the SEL
input sets the default state of the switch.
