Описание

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 RON 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.

Ultra Low R_ON for GND Switch (80-mΩ typical)
R_ON for MIC Switch <10-Ω
3.0V to 3.6V V+ Operation
Control Input is 1.8-V Logic Compatible
