M74HC4851

The M74HC4851 device is a single 8-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 voltages 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.
