Description

General part information

SN74HC4851-Q1 Series

This eight-channel CMOS analog multiplexer/demultiplexer is terminal compatible with the function of the ’4051 device, and features injection-current effect control, which has excellent value in automotive applications where voltages in excess of normal supply voltages are common.

The injection-current effect control allows signals at disabled analog input channels to exceed the supply voltage without affecting the signal of the enabled analog channel. This feature eliminates the need for external diode/resistor networks typically used to keep the analog channel signals within the supply-voltage range.
