Description
The PI3A3159 is a, 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
range, +1.5V to +3.6V, the PI3A3159 has an On-Resistance of
0.4Ω at 3.0V.
Control input, IN, tolerates input drive signals up to 3.3V, inde-
pendent of supply voltage.
PI3A3159 is a lower voltage and On-Resistance replacement for
the PI5A3159.
