Overview
The CD74HC4067SM96E4 is a 16:1 single-channel analog multiplexer and demultiplexer produced by Texas Instruments. This device utilizes silicon-gate CMOS technology, offering operating speeds similar to LSTTL logic while maintaining the low power consumption of standard CMOS integrated circuits. It is designed to control analog voltages across the entire voltage supply range and features bidirectional switches, allowing any analog input to be used as an output and vice versa. The device includes an enable control that disables all switches when set high.
