PI3A412
0.4, 3.3V, Quad SPDT Analog Switch
Description
The PI3A412 is a quad 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, +1.6V to +4.2V, the switch has an On-Resistance of 0.4
at 2.7V.
Control inputs, Ax, tolerates input drive signals up to 5V, indepen-
dent of supply voltage.
