Description
TPW4157 is high performance Single Pole/Double Throw
(SPDT) analog switches. The devices feature ultra low RON of
1.15Ω maximum at 4.5V V
CC
and will operate over the wide V
CC
range of 1.65V to 5.5V.
The TPW4157 features very low quiescent current even when
the control voltage is lower than the V
CC
supply. This feature
services the portable applications very well allowing for the
direct interface with processor general purpose I/Os.
Applications
Industry control systems
Battery-powered systems
Audio Signal Routing
Portable Instruments and Mobile Device
