Description

The M74HC4852 device is a dual four-channel

analog multiplexer/demultiplexer manufactured

with silicon gate C

MOS 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 diode-

resistor networks typically used to keep the

analog channel signals within the supply voltage

range.
