description/ordering information
This eight-channel CMOS analog multiplexer/demultiplexer is pin compatible with the ’4051 function and,
additionally, 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 eliminates the need for external
diode/resistor networks typically used to keep the analog channel signals within the supply-voltage range.
