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