Description
Pericom Semiconductor's PI3A212 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
wide operating power supply voltage, 2.7V to 4.2V, the PI3A212
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.
