Description

The PI5A3166 is a high-bandwidth, fast single-pole

single-throw (SPST) 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 PI5A3166 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.

The control input, S, is independent of supply voltage.
