The SN74HC4066 device is a silicon-gate CMOS quadruple analog switch designed to handleboth analog and digital signals. Each switch permits signals with amplitudes of up to 6 V (peak) tobe transmitted in either direction.
Each switch section has its own enable input control (C). A high-level voltage applied toC turns on the associated switch section.
Applications include signal gating, chopping, modulation or demodulation (modem), andsignal multiplexing for analog-to-digital and digital-to-analog conversion systems.
