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.
