Product Overview
74HC4051BQ,115 is the compact DHVQFN16 orderable of Nexperia’s 74HC4051 eight-channel analog multiplexer/demultiplexer. Three binary select inputs connect one of eight Y channels to the common Z node, and the enable input opens all switch paths when asserted HIGH.
The device is bidirectional, so it can be used as either an 8-to-1 multiplexer or a 1-to-8 demultiplexer. The QFN package is useful where the same 4051 switching function is needed in substantially less board area than a leaded SO16 option.

Multiplexer Integration Considerations
The analog channel voltage must remain within the permitted supply rails. When bipolar analog signals are required, the VEE connection and logic thresholds need to be planned together rather than treating the device as a simple single-supply logic mux.
For BOM control, the BQ package code and ,115 packing suffix should be retained because other 74HC4051 orderables use different footprints.
