The HEF4067B-Q100 is a 16-channel analog multiplexer/demultiplexer. It has four
address inputs (A0 to A3), an active LOW enable input (E), 16 independent inputs/outputs
(Y0 to Y15) and a common input/output (Z). The device contains 16 bidirectional analog
switches. Each switch has 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 16 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 analog 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 3) and is suitable for use in automotive applications.
