Overview
The CD74HCT4067MG4 is a high-speed CMOS logic 16-channel analog multiplexer/demultiplexer 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. The CD74HCT4067MG4 is designed to control analog voltages that may vary across the voltage supply range and features bidirectional switches, allowing any analog input to be used as an output and vice versa.
