3 Description

The CD74HCT4066-Q1 contains four independent

digitally controlled analog switches that use silicongate

CMOS technology to achieve operation 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. Each switch is

turned on by a high-level voltage on its control input.
