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.
