LoPro™ Dual SPDT Analog Switch
ANALO G P RO DUCTS DIVIS IO N
Features
Description
CMOS Technology for Bus and Analog Applications
ProTek Analog’s PA2312 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 operating power supply voltage, 1.8V to
4.2V, the PA2312 has an On-Resistance of 0.6Ω at +2.7V.
Break-before-make switching prevents both switches being
enabled simultaneously. This eliminates signal disruption
during switching.
Low On-Resistance: 0.6Ω.

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 input and output diode current ratings are observed.
Control input must be held HIGH or LOW; it must not float
