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.
