3 Description

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.
