PI3A412E
0.5Ω, 3.3V, Quad SPDT Analog Switch with Enable
Description
The PI3A412E is a Quad single-pole double-throw (SPDT) CMOS
switch with enable. It can be used as an analog switch or as a low-
delay bus switch. Specied over a wide operating power supply
voltage range, +1.65V to +4.2V, the switch has an On-Resistance
of 0.5Ω at 2.7V.
Control inputs, A0 to EN, tolerates input drive signals up to 5V,
independent of supply voltage.
