TPW4157 is high performance Single Pole/Double Throw(SPDT) analog switches. The devices feature ultra low RON of 1.15Ω maximum at 4.5V VCC and will operate over the wide VCC range of 1.65V to 5.5V.

   The TPW4157 features very low quiescent current even when the control voltage is lower than the VCC supply. This feature services the portable applications very well allowing for the direct interface with processor general purpose I/Os.
