Automotive, 5V, 4:1, 2-channel, analog multiplexer, injection current control

This dual 4-to-1 CMOS analog

multiplexer/demultiplexer is pin compatible with the 4052 function and also features

injection-current effect control. This feature 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.
