Description
Pericom Semiconductor's PI5A4213 is a dual high-bandwidth,
fast single-pole triple throw (SP3T) CMOS switch. It can be used
as an analog switch or as a low-delay bus switch. The PI5A4213
is specified over a wide operating power supply voltage, 1.65V
to 5.5V.
Break-before-make switching prevents both switches being en-
abled simultaneously. This eliminates signal disruption during
switching.
The control input, S, tolerates input drive signals up to 6.0V,
independent of supply voltage.
