The device contains eight bidirectional analogue switches, each with one side connected to an independent input/output (Y0 to Y7) and the other side connected to 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.
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.
HEF4051B MSI 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).
