Description
ProTek Analog’s PA2222 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 PA2222 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.
The PA2222T includes termination resistors that improve
noise immunity during overshoot excursions and off isolations
or pop-up noise minimization

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.
3. Control input must be held HIGH or LOW; it must not float.
4. Internal Resistance RTERM is guaranteed by design and not production tested.
