Description

The PI5A3158B 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.

Specified over a wide operating power supply voltage

range, 1.65V to 5.5V, the PI5A3158B has a maximum

ON resistance of 12-ohms at 1.65V, 9-ohms at 2.3V &

6-ohms at 4.5V.

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.

Application



Cell Phones



PDAs



MP3 Players



Portable Instrumentation



Battery powered Communications


