Overview
The CD74HC4066PWG4, produced by Texas Instruments, is a high-speed CMOS logic quad bilateral switch. This device contains four independent digitally controlled analog switches, utilizing silicon-gate CMOS technology to achieve operating speeds similar to LSTTL with the low power consumption of standard CMOS integrated circuits. Each switch is turned on by a high-level voltage on its control input, and they feature the characteristic linear ON resistance of the metal-gate CD4066B device.
