Overview
The CD74HC4066PWT is a high-speed CMOS logic quad bilateral switch produced by Texas Instruments. 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 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.
