DESCRIPTION

The HEF4067B is a 16-channel analogue

multiplexer/demultiplexer with four address inputs (A0 to

A3), an active LOW enable input (E), sixteen independent

inputs/outputs (Y0 to Y15) and a common input/output (Z).

The device contains sixteen bidirectional analogue

switches, each with one side connected to an independent

input/output (Y0 to Y15) and the other side connected to

the common input/output (Z).

With E LOW, one of the sixteen switches is selected (low

impedance ON-state) by A0 to A3. All unselected switches

are in the high impedance OFF-state. With E HIGH all

switches are in the high impedance OFF-state,

independent of A0 to A3.

The analogue inputs/outputs (Y0 to Y15 and Z) can swing

between VDD as a positive limit and VSS as a negative

limit. VDD to VSS may not exceed 15 V.
