Overview
The CD74HCT4051M96G4 is a digitally controlled analog switch produced by Texas Instruments. This device utilizes silicon gate CMOS technology to achieve operating speeds similar to LSTTL with the low-power consumption of standard CMOS integrated circuits. It functions as an analog multiplexer and demultiplexer, controlling analog voltages that may vary across the voltage supply range (e.g., VCC to VEE). The CD74HCT4051 is a bidirectional switch, allowing any analog input to be used as an output and vice versa, with features such as low ON resistance, low OFF leakages, and an enable control that disables all switches when high.
