Overview
The MC74HC4051ADTG, produced by onsemi, is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer. This device is part of the HC4051A series, which includes the MC74HC4051A, MC74HC4052A, and MC74HC4053A. These multiplexers utilize advanced CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. They are designed to control analog voltages across the complete power supply range, from VCC to VEE. The MC74HC4051ADTG is identical in pinout to the metal-gate MC14051AB and is compatible with standard CMOS and LSTTL outputs with pullup resistors.
