Analog Switches

SPDTanalog switchUSB 2.0700 MHz1.8 V logicDFN1109-6

WAS3157D is a 6-pin SPDT analog signal switch for selecting B0 or B1 to common terminal A. Its 700 MHz typical bandwidth supports USB 2.0 High-Speed routing when the layout is suitable.

Best for

  • USB 2.0 signal routing
  • Low-voltage audio, video, or UART switching
  • Compact portable electronics

Avoid if

  • The application requires a documented automotive qualification
  • The signal or supply voltage exceeds 5.5 V
  • A verified lifecycle or compliance declaration is mandatory

Check before use

  • SEL low selects B0 and SEL high selects B1
  • Confirm analog signal voltage limits for all switch terminals
  • Validate DFN1109-6 PCB footprint and assembly capability
