Overview
The CD74HC4066EG4 is a high-speed CMOS logic quad bilateral switch produced by Texas Instruments. This device is part of the 74HC series and is designed to operate with the low power consumption of standard CMOS integrated circuits while achieving operating speeds similar to LSTTL (Low-power Schottky Transistor-Transistor Logic).
The CD74HC4066EG4 features four independent digitally controlled analog switches, each with two input/output terminals and an active HIGH enable input. This makes it suitable for a wide range of analog and digital signal switching and multiplexing applications.
