8-CHANNEL ANALOG MULTIPLEXER/DEMULTIPLEX ER WITH

INJECTION-CURRENT EFFECT CONTROL

DESCRIPTION

The U74HC4851 contains an 8-channel analog

multiplexer/demultiplexer with 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

eliminates the need for external diode/resistor networks typically

used to keep the analog channel signals within the

supply-voltage range.

FEATURES

* Injection-Current cross coupling<1mV/mA

* Low crosstalk between switches

* 2V to 6V VCC Operation
