Overview
The MC74HC4053A, produced by onsemi, is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer. This device utilizes advanced CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. It is designed to control analog voltages that can vary across the complete power supply range (from VCC to VEE). The MC74HC4053A is identical in pinout to the metal-gate MC14053AB and features channel-select inputs that determine which analog input/output is connected to the common output/input. The device also includes an enable pin that turns off all analog switches when set to HIGH.
