Overview
The MC74HC4066A, produced by onsemi, is a high-performance silicon-gate CMOS quad analog switch/multiplexer/demultiplexer. This device utilizes advanced 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 HC4066A is pin-compatible with the metal-gate CMOS MC14016 and MC14066, and each device includes four independent switches. The ON resistances (RON) of the HC4066A are more linear over input voltage compared to metal-gate CMOS analog switches, making it a reliable choice for various applications.
