Overview
The CD74HC4066PWR, manufactured by Texas Instruments, is a high-speed CMOS logic quad bilateral switch. This device contains four independent digitally controlled analog switches that utilize silicon-gate CMOS technology. This technology allows the switches to achieve operating speeds similar to LSTTL (Low-power Schottky Transistor-Transistor Logic) while maintaining the low power consumption characteristic of standard CMOS integrated circuits. Each switch is turned on by a high-level voltage on its control input and features the linear ON resistance of the metal-gate CD4066B device.
