XD4059 – CMOS Programmable Divide-by-N Counter – Xinluda

The Xinluda XD4059 is a DIP-24 CMOS programmable divide-by-N counter that divides an input frequency by any integer N from 3 to 15,999, functionally equivalent to the classic CD4059A. Available for RFQ from Pacific Component Xchange.

The XD4059 from Xinluda (Shenzhen Xinluda Information Technology Co., Ltd.) is a CMOS programmable divide-by-N counter housed in a 24-pin DIP package. It is a divide-by-N down-counter that can be programmed to divide an input frequency by any number “N” from 3 to 15,999, producing an output pulse one clock-cycle wide at a rate equal to the input frequency divided by N. The XD4059 is functionally and pin-compatible with the industry-standard CD4059A, making it a convenient drop-in replacement for legacy designs.

The down-counter is preset by means of 16 jam inputs, and three mode-select inputs (Ka, Kb, Kc) determine the modulus of the first and last counting sections. An intermediate counting section is formed from cascaded BCD decade counters. The device provides a TTL-compatible output, allowing it to interface readily with mixed CMOS/TTL systems.

Why Source XD4059 from Pacific Component Xchange

The XD4059 is a specialty, hard-to-find component with little to no authorized-distributor availability. Pacific Component Xchange is an independent distributor that specializes in sourcing scarce and obsolete logic, power-management ICs, and optocouplers. We help engineers and buyers locate XD4059 inventory when mainstream channels show it as unavailable.

Every part we supply is screened for authenticity to protect your build against counterfeit risk, and we ship globally to support production lines and prototype runs alike. Because pricing on hard-to-find parts moves with supply, the XD4059 is offered on a request-for-quote basis. Contact Pacific Component Xchange today to submit an RFQ for the Xinluda XD4059 and get current availability and lead-time information.
