Overview
The MC74HCT4851ADR2G is an analog multiplexer/demultiplexer (mux/demux) integrated circuit produced by onsemi. This device is designed to be pin compatible with standard HC4051 and MC14051B analog mux/demux devices but features advanced injection current effect control. This makes it particularly suitable for automotive applications where voltages can exceed normal logic voltage levels. The injection current effect 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.
