Overview
The CD74HC4067SM96 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 a 16:1 analog multiplexer and demultiplexer, allowing control over analog voltages that may vary across the voltage supply range. The device is bidirectional, enabling any analog input to be used as an output and vice versa. It features low on resistance, low off leakages, and an enable control that disables all switches when high.
