XD14051 – Analog Multiplexer/Demultiplexer – Xinluda

The Xinluda XD14051 is a digitally controlled single 8-channel analog multiplexer/demultiplexer (SP8T) in a DIP-16 package, pin-for-pin compatible with the industry-standard MC14051B/CD4051.

The XD14051 from Xinluda is a digitally controlled analog multiplexer/demultiplexer that implements a single-pole, 8-throw (SP8T) solid-state switch. It steers one of eight analog or digital inputs to a common output (or vice versa) under control of three binary address inputs plus an active-low inhibit (enable) line. The device is a direct functional and pin-compatible alternative to the long-running industry-standard MC14051B and CD4051 4000-series CMOS multiplexers, making it a convenient drop-in for legacy and cost-sensitive designs.

Built on a CMOS process, the XD14051 offers low ON impedance and very low OFF-state leakage current, allowing it to pass analog signals across the full supply-voltage range with minimal distortion. On-chip triple-diode protection guards the control inputs, and the break-before-make switching action helps prevent channel cross-conduction during address transitions.
