Overview
The MC74HC4052ADG is a high-performance analog multiplexer/demultiplexer produced by onsemi. This device utilizes silicon-gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. It is designed to control analog voltages across the complete power supply range from VCC to VEE. The MC74HC4052A is part of a family that includes the HC4051A and HC4053A, all of which are identical in pinout to their metal-gate counterparts but offer improved linearity and lower ON resistance.
