PI5A4213
Low Voltage Dual SP3T Analog Switch
3:1 Mux/DeMux Bus Switch
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.

Notes:
1. Absolute Maximum Ratings may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any
other conditions beyond those indicated in the operational sections of this specification is not implied.
2. The input and output negative voltage ratings may be exceeded if the inut and output diode current ratings are observed.
3. Control input must be held HIGH or LOW; it must not float.
