Overview
The MC74HC4852ADR2G is an analog multiplexer/demultiplexer device produced by onsemi. It is particularly designed for automotive applications where voltages can exceed normal logic voltage levels. This device is pin compatible with standard HC405x and MC1405xB analog mux/demux devices but features advanced injection current effect control. This control allows signals at disabled analog input channels to exceed the supply voltage range without affecting the signal of the enabled analog channel, eliminating the need for external diode/resistor networks.
The MC74HC4852ADR2G utilizes low power silicon gate CMOS technology and has Channel Select and Enable inputs that are compatible with standard CMOS outputs.
