The MC14066B is a quad analog switch/quad multiplexer consisting of four independent switches capable of controlling either digital or analog signals. This quad bilateral switch is useful in signal gating, chopper, modulator, demodulator and CMOS logic implementation.
The MC14066B quad analog switch/multiplexer provides four independent bilateral switches for digital or analog signals. It supports supply voltages from 3 V to 18 V and features triple‑diode protection on all control inputs.
The device is pin‑compatible with the MC14016B and offers lower ON resistance. Detailed electrical characteristics, maximum ratings, package dimensions, and ordering information are provided for designers.
