Description
The PI5A3157 is a 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 PI5A3157 has a maximum
ONresistanceof 12-ohmsat1.65V,9-ohmsat2.3V&6-ohmsat4.5V.
Break-before-make switching prevents both switches being
enabled simultaneously. This eliminates signal disruption during
switching.
The control input, S, tolerates input drive signals up to 5.5V,
independent of supply voltage.
PI5A3157 is an improved direct replacement for the NC7SB3157.

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.
