Part Number	HEF4051B Datasheet
Manufacturer	NXP Semiconductors
Overview	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/out. ependent 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.
