Product data sheet
1. General description
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.
