The PI5A4158 is a dual high-bandwidth, fast single-pole
double-throw (SPDT) CMOS switch. It can be used as
an analog switch or as a low-delay bus switch. The
device features ultra low RON of 0.8Ω typical at 3.0V
VCC and will operate over the wide VCC range of
1.65V to 5.5V.
The PI5A4158 features very low quiescent current even
when the control voltage is lower than the VCC supply.
This feature services the mobile handset applications
very well by allowing direct interface with baseband
processor general purpose I/Os.
Break-before-make switching prevents both switches
being enabled simultaneously. This eliminates signal
disruption during switching.
The control input, S, is independent of supply voltage.
