DESCRIPTION
– 2000-V Human-Body Model (A114-B, Class
The TS3A26746E is a 2 × 2 cross-point switch that is

used to interchange the Ground and MIC connections
– 500-V Charged-Device Model (C101)
on a headphone connector. The Ground switch has
an ultra low R
ON
of <0.1Ω to minimize voltage drop
• ESD Performance (SLEEVE, RING2)
across it, preventing undesired increases in

headphone ground reference voltage. The switch
state is controlled via the SEL input. When
APPLICATIONS
SEL=High, GND is connected to RING2 and MIC is
connected to SLEEVE. When SEL=Low, GND is
