Description
Pericom Semiconductor's PI3A223 is a dual, 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, 2.7V to 4.2V, the PI3A223 has an On-Resistance
of 0.6Ω at +2.7V.
Break-before-make switching prevents both switches being en-
abled simultaneously. This eliminates signal disruption during
switching.
