The Xinluda XD4051 is a CMOS 8-channel analog multiplexer/demultiplexer belonging to the industry-standard 4051 family. It steers a single common line to any one of eight independent analog channels, with channel selection controlled by three binary address inputs (A, B, C) and a single inhibit (INH) input. Driving INH high turns all channels off, placing the device in a high-impedance state. Because the analog path is bilateral, the XD4051 works equally well as a multiplexer or a demultiplexer.
The device features a built-in binary address decoder with break-before-make switching, so that low-voltage digital control logic can switch a much wider analog signal swing, making it well suited to mixed-signal designs where logic supplies and analog rails differ. It is offered in a through-hole DIP-16 package.
The XD4051 is a Xinluda-branded part with limited authorized-distributor coverage, which can make it difficult to source through mainstream channels. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs, analog switches, and optocouplers. We help engineers and buyers secure allocation-constrained and end-of-life components with authenticity verification and global shipping.

The XD4051 is an 8-channel CMOS analog multiplexer/demultiplexer in the industry-standard 4051 family. It connects a single common line to any one of eight analog channels selected by three binary address inputs plus an inhibit input.
No. Despite occasional misclassification, the XD4051 is not a regulator. It is an 8-channel single-pole, 8-throw bilateral analog switch/multiplexer (4051-type).
The XD4051 listed here is supplied in a DIP-16 through-hole package.
The XD4051 operates over a wide supply range of 3 V to 20 V, with a digital control voltage range of 4.5 V to 18 V and analog signal handling up to 18 V.
Driving the INH input high turns all eight channels off, placing the multiplexer in a high-impedance state regardless of the address inputs.
Yes. The analog signal path is bilateral, so the device can route a signal in either direction, functioning as either a multiplexer or a demultiplexer.
The XD4051 is a hard-to-find, request-for-quote item. Submit an RFQ through Pacific Component Xchange and our sourcing team will respond with current availability, pricing, and lead time.
