The HEF4051B is an 8-channel analogue multiplexer/demultiplexer with three address inputs (A0 to A2), an active LOW enable input (E), eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z). With E LOW, one of the eight switches is selected (low impedance ON-state) by A0 to A2. With E HIGH, all switches are in the high impedance OFF-state, independent of A0 to A2. The device contains eight bidirectional analogue switches, each with one side connected to an independent input/output (Y0 to Y7) VDD and VSS are the supply voltage connections for the digital control inputs (A0 to A2, and E). The VDD to VSS range is 3 to 15 V. The analogue inputs/outputs (Y0 to Y7, and Z) can swing between VDD as a positive limit and VEE as a negative limit. VDD-VEE may not exceed 15 V. For operation as a digital multiplexer/demultiplexer, VEE is connected to VSS (typically ground). Fig.2 Pinning diagram.

To avoid drawing VDD current out of terminal Z, when switch current flows into terminals Y, the voltage drop across the bidirectional switch must not exceed 0,4 V. If the switch current flows into terminal Z, no VDD current will flow out of terminals Y, in this case there is no limit for the voltage drop across the switch, but the voltages at Y and Z may not exceed VDD or VEE.
