XD4051 – Analog Multiplexer / Switch – Xinluda

The Xinluda XD4051 is an 8-channel single-pole, 8-throw CMOS analog multiplexer/demultiplexer (4051-family) in a DIP-16 package, selecting any one of eight analog channels via three binary address inputs plus an inhibit pin.

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.

Key Features

• 8-channel single-pole, 8-throw bilateral analog multiplexer/demultiplexer (4051-type)
• Channel selection via 3 binary address inputs (A, B, C) plus an inhibit (INH) input
• Inhibit input disables all channels for a high-impedance off state
• Wide supply voltage range: 3 V to 20 V
• Wide control/transmission range: digital control 4.5 V to 18 V, analog signal up to 18 V
• Low on-resistance (approximately 80 ohm typical) with high off-resistance and low off-channel leakage
• Built-in binary address decoder with break-before-make switching
• Operating temperature range: -40 C to +85 C
• DIP-16 through-hole package

Applications

• Analog signal routing and channel selection
• Data-acquisition and ADC front-end multiplexing
• Sensor and instrumentation input switching
• Audio and communications signal gating
• Digital-to-analog demultiplexing and general signal steering

Why Source XD4051 from Pacific Component Xchange

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.
