74VHC4066N

Analog Switches, Multiplexers, Demultiplexers Overview

The Fairchild Semiconductor 74VHC4066N is a quad analog switch utilizing advanced silicon-gate CMOS technology. It features low on-resistance and low off-leakage currents, with bidirectional signal capability allowing any input to serve as an output. The device includes linearization circuitry to enhance switch linearity and supports analog signals up to 12V peak controlled by digital signals of the same range. Each switch has independent control inputs that disable the channel when low. Electrostatic protection diodes are integrated for all analog and digital pins. Key electrical parameters include a typical on-resistance of 30 ohms, a maximum quiescent current of 80 pA, and a typical enable time of 15 ns.
