Overview
The MC74HCT4051ADR2G, produced by onsemi, is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer. This device is part of the 74HCT series and is designed to control analog voltages across a wide power supply range (from VCC to VEE), making it versatile for various analog switching applications. The MC74HCT4051A is identical in pinout to the metal-gate MC14051AB and features fast propagation delays, low ON resistances, and low OFF leakage currents. The Channel-Select inputs determine which analog input/output is connected to the common output/input via an analog switch, and all switches are turned off when the Enable pin is HIGH.
