Description

The M74HC4852 is a dual four-channel analog multiplexer/demultiplexer manufactured with silicon gate C2MOS technology.

It features injection current effect control which makes the device particularly suited for use in automotive applications where voltages in excess of normal logic voltage are common. The injection current effect control allows signals at disabled input channels to exceed the supply voltage range or go down to ground without affecting the signal of the enabled analog channel.

This eliminates the need for external dioderesistor networks typically used to keep the analog channel signals within the supply voltage range.
