The Xinluda XD14518 is a CMOS dual BCD up counter from the popular 4000-series logic family, supplied in a through-hole 16-pin DIP package. It is a pin-for-pin and functional equivalent of the industry-standard CD4518 / MC14518 dual decade counter, making it a convenient drop-in option for legacy and cost-sensitive digital designs. Each device integrates two identical, independent, and internally synchronous 4-stage counters built from D-type flip-flops.
Each counter offers interchangeable CLOCK and ENABLE lines, allowing the stage to increment on either a positive-going or negative-going transition. For single-unit operation the ENABLE input is held high and the counter advances on each rising edge of the CLOCK. A master RESET input clears all four stages of a counter to zero independently. The wide CMOS supply range and diode-protected inputs make the XD14518 well suited to timers, frequency dividers, and general-purpose counting applications.
The Xinluda XD14518 sees little to no authorized-distributor stock, which makes it difficult to source through mainstream channels. Pacific Component Xchange specializes in hard-to-find and obsolete logic and power-management ICs, giving engineers and buyers a reliable path to the parts they need. Every order is backed by our authenticity and quality assurance process, with worldwide shipping to keep your production line moving.

The XD14518 is a CMOS dual BCD (decade) up counter from Xinluda, part of the 4000-series logic family. It contains two identical, independent, internally synchronous 4-stage counters in a single 16-pin DIP package.
Yes. The XD14518 is functionally and pin-compatible with the industry-standard CD4518 / MC14518 dual BCD up counter, so it can generally be used as a drop-in replacement in 4518-based designs.
Xinluda supplies the XD14518 in a 16-pin DIP (dual in-line, through-hole) package.
Per the Xinluda datasheet, the XD14518 operates over a wide supply range of 3 V to 18 V. Confirm exact limits against the manufacturer datasheet for your design conditions.
It is used in decade and BCD counting circuits, frequency dividers, digital timers, time-base generators, and general-purpose pulse/event counting applications.
