The 74HC/HCT4066 are high-speed Si-gate CMOS devices and are pin compatible with the “4066” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT4066 have four independent analog switches. Each switch has two input/output terminals (nY, nZ) and an active HIGH enable input (nE). When nE is LOW the belonging analog switch is turned off.
The Philips 74HC/HCT4066 is a quad bilateral switch family built on high‑speed Si‑gate CMOS technology. Each of the four independent analog switches has two I/O terminals and an active‑HIGH enable input. The devices are pin compatible with the classic 4016 part of the 4000B series.
The data sheet provides detailed electrical characteristics, ordering information, package options, and guidelines for soldering methods. It also includes absolute maximum ratings, recommended operating conditions, and application notes for reliable use in digital and low‑power analog circuits.
