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 lowdelay bus switch. Specified over a wide operating power supply voltage range, +1.65V to +4.2V, the switch has an On-Resistance of 0.5 at 2.7V. Control inputs, A0 to EN, tolerates input drive signals up to 5V, independent of supply voltage.
