Overview
The MC74HC4051ADWG, produced by onsemi, is a high-performance analog multiplexer/demultiplexer that utilizes silicon-gate CMOS technology. This device is designed to control analog voltages that may vary across the complete power supply range (from VCC to VEE). It is identical in pinout to the metal-gate MC14051AB and offers fast propagation delays, low ON resistances, and low OFF leakage currents. The Channel-Select inputs determine which one of the Analog Inputs/Outputs is connected to the Common Output/Input, and the Enable pin controls the state of all analog switches.
