Nexperia 74HC4051BQ
8‑Channel Analog Mux/Demux
DHVQFN16
New UK Stock
Genuine Nexperia 74HC4051BQ 8‑channel analog multiplexer/demultiplexer in compact DHVQFN16 packaging. Ideal for routing precision analog or digital signals, the 74HC4051BQ provides a single‑pole, eight‑throw (SP8T) switch configuration for flexible 8:1 multiplexing and demultiplexing in space‑constrained PCBs.
The device operates from a wide 2 V to 10 V supply range and supports an analog voltage span of approximately −5 V to +5 V (VEE to VCC), making it suitable for both unipolar and bipolar signal paths. With typical on‑resistance around 70–80 Ω (depending on supply voltage) and propagation delays in the nanosecond range, it is well‑suited to high‑speed switching and low‑distortion signal routing applications.
Three CMOS‑compatible address lines (S0, S1, S2) plus an enable input (E) provide simple logic control from microcontrollers, FPGAs, or standard logic families. A built‑in break‑before‑make characteristic helps prevent channel overlap, while integrated ESD protection improves robustness in demanding environments.
Supplied in the ultra‑low‑profile DHVQFN16 (SOT763‑1) package, the 74HC4051BQ is perfect for high‑density designs where every millimetre of board space counts. Typical applications include sensor selection, audio and video routing, data acquisition front‑ends, test and measurement equipment, and general‑purpose signal gating in embedded systems.
This listing is for brand new, unused stock with the UPC 935273693115, ideal for both prototyping and production builds. Multiple units can be ordered; volume buyers benefit from combined postage and consistent batch sourcing to simplify inventory and assembly.
