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.
