Overview
The NLV74HC4851ADR2G is an analog switch, multiplexer, and demultiplexer integrated circuit designed for interface applications, particularly in the automotive sector. This device is part of the HC series from onsemi and is known for its pin compatibility with standard HC405x and MC1405xB analog mux/demux devices. It features injection current effect control, which is crucial for handling signals that exceed the normal logic voltage range, common in automotive environments. This eliminates the need for external diode/resistor networks to keep analog channel signals within the supply voltage range.
The device utilizes low power silicon gate CMOS technology and has Channel Select and Enable inputs that are compatible with standard CMOS outputs.
