Description

TPW3221 is high performance Single Pole/Double Throw

(SPDT) analog switches. The devices feature ultra low RON of

1.2Ω maximum at 4.5V VCC and will operate over the wide VCC

range of 1.65V to 5.5V.

The TPW3221 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.

The TPW3221 has very excellent channel to channel crosstalk

performance to fit the application with high channel to channel

isolation requirement.
