Overview
The MC74HC4066DTEL, produced by onsemi, is a high-performance silicon-gate CMOS quad single-pole single-throw (SPST) analog switch. This device is designed to control both analog and digital voltages across a wide power-supply range, from 2.0 to 12.0 volts. It features four independent switches, each with two input/output terminals and an active HIGH enable input. The MC74HC4066DTEL is identical in pinout to the metal-gate CMOS MC14016 and MC14066, and it offers improved linearity and lower ON resistance compared to its metal-gate counterparts.
