Specified over a wide operating power supply voltage range, 2.3V to 3.6V, the PI3A125 has a low maximum ON resistance of 10-ohm at 2.3V and 7 ohms at 3V. The CMOS device features rail-to-rail signal range. The switch is turned off when the OE input is high. Power requirements at 3V are a low 30W. The PI3A125 is an improved, direct replacement for the SN74CBTLV1G125. Pericom improvements include lower resistance and detailed analog switch specifications.
