The HEF4051B is an 8-channel analog multiplexer/demultiplexer
with three addressinputs (S1 to S3), an active LOW enable input (E),
eight independent inputs/outputs(Y0 to Y7) and a common input/output (Z).

VDD and VSS are the supply voltage connections for the digital control inputs (S1 to S3,
and E). The VDD to VSS range is 3 V to 15 V. The analog inputs/outputs (Y0 to Y7, and Z)
can swing between VDD as a positive limit and VEE as a negative limit. VDD
VEEmay not exceed 15 V. Unused inputs must be connected to VDD, VSS, or another input. For
operation as a digital multiplexer/demultiplexer, VEE is connected to VSS(typically ground). VEE and VSS
are the supply voltage connections for the switches
