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
