2 x 2 crosspoint switch for audio applications - TS3A26746E


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 RON for GND Switch (80-mΩ typical)
  • RON for MIC Switch <10-Ω
  • 3.0V to 3.6V V+ Operation
  • Control Input is 1.8-V Logic Compatible
  • 6-bump, 0.5mm pitch CSP Package (1.45mm × 0.95mm × 0.5mm)
  • Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
  • ESD Performance Tested Per JESD 22
    • 2000-V Human-Body Model (A114-B, Class II)
    • 500-V Charged-Device Model (C101)
  • ESD Performance (SLEEVE, RING2)
    • ±8-kV Contact Discharge (IEC 61000-4-2)
