Recommended alternative parts

  • TS5A23167  -  Same as TS5A23166 but is Normally Closed.
  • TS5A21366  -  Similar to TS5A23166 but has 1.8V compatible control inputs.


The TS5A23166 device is a dual single-pole single-throw (SPST) analog switch that is designed to operate from 1.65 V to 5.5 V. The TS5A23166 device offers a low ON-state resistance and an excellent channel-to-channel ON-state resistance matching. The TS5A23166 device has excellent total harmonic distortion (THD) performance and consumes very low power. These features make this device suitable for portable audio applications.
