Overview
The MC74HC4051ADWR2G, produced by onsemi, is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer. This device is part of the HC4051A series, which includes the HC4051A, HC4052A, and HC4053A. These multiplexers utilize silicon-gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. They control analog voltages that can vary across the complete power supply range from VCC to VEE. The HC4051A is identical in pinout to the metal-gate MC14051AB and offers improved linearity and lower ON resistance compared to its metal-gate counterparts.
