Overview
The MC74HC4051ADTR2G is a high-performance analog multiplexer/demultiplexer produced by onsemi. This device utilizes silicon-gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. It is designed to control analog voltages that may vary across the complete power supply range from VCC to VEE. The MC74HC4051A is identical in pinout to the metal-gate MC14051AB and features Channel-Select inputs that determine which one of the Analog Inputs/Outputs is connected to the Common Output/Input via an analog switch. When the Enable pin is HIGH, all analog switches are turned off.
