Overview
The CD74HC4051-Q1 is a digitally controlled analog switch produced by Texas Instruments. This device utilizes silicon-gate CMOS technology to achieve operating speeds similar to LSTTL, while maintaining the low power consumption characteristic of standard CMOS integrated circuits. It functions as an analog multiplexer/demultiplexer, controlling analog voltages that may vary across the voltage supply range. The device features bidirectional switches with low ON resistance and low OFF leakages, and includes an enable control that disables all switches when set high.
