The ’HC4066 and CD74HCT4066 devices contain four independent digitally controlled analog switches that use silicon-gate CMOS technology to achieve operating speeds similar to LSTTL with the low power consumption of standard CMOS integrated circuits.

These switches feature the characteristic linear ON resistance of the metal-gate CD4066B device. Each switch is turned on by a high-level voltage on its control input.
