Overview
The CD74HC4067M96G4 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-channel analog multiplexer/demultiplexer, allowing for the control of analog voltages 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 set high.
