Description
The PI3A125 is a high-speed CMOS SPST switch that can be used
in analog or low-delay bus switch applications.
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 30µW.
The PI3A125 is an improved, direct replacement for the
SN74CBTLV1G125. Pericom improvements include lower resis-
tance and detailed analog switch specifications.
