Overview
The MC74HC4066DT, produced by onsemi, is a quad single-pole single-throw (SPST) analog switch/multiplexer/demultiplexer. This device utilizes silicon-gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF-channel leakage current. It is designed to control both analog and digital voltages across the full power-supply range from VCC to GND. The MC74HC4066DT is identical in pinout to the metal-gate CMOS MC14016 and MC14066, making it a versatile component for various applications.
