The XD555 from Xinluda is a single-chip CMOS timing circuit that delivers the classic 555 timer function with significantly lower power consumption. Built on a CMOS process, it is fully compatible with CMOS, TTL, and MOS logic and is functionally interchangeable with the industry-standard 555NE, making it a convenient drop-in upgrade for legacy designs that need reduced supply current and rail-to-rail output swing. Thanks to its high input impedance, the XD555 can operate at frequencies up to 2 MHz and works with smaller timing capacitors than a bipolar 555NE, enabling more precise delay and oscillation timing.
The Xinluda XD555 is a hard-to-find part with little to no authorized-distributor stock in North America. Pacific Component Xchange specializes in sourcing scarce and obsolete power-management ICs, timers, and optocouplers from a vetted global supply network. Every order is screened for authenticity and quality, and we ship worldwide. If you have an end-of-life design, an urgent line-down situation, or simply cannot find the XD555 through standard channels, request a quote (RFQ) from Pacific Component Xchange and our sourcing team will locate verified inventory at competitive pricing.
The XD555 is a low-power CMOS single-timer IC from Xinluda. It performs the same astable and monostable timing functions as a classic 555 timer but with much lower power consumption and a CMOS rail-to-rail output.
Yes. The XD555 is functionally interchangeable with the 555NE and its outputs are compatible with CMOS, TTL, and MOS logic, so it can serve as a low-power drop-in alternative in many 555-based designs.
The XD555 documented here is supplied in a DIP-8 (8-pin dual in-line) through-hole package and is RoHS compliant.
It operates from a single supply of 2 V to 15 V and, due to its high input impedance, can operate at frequencies up to 2 MHz. Typical power consumption is around 1 mW at VDD = 5 V.
Xinluda parts like the XD555 have limited authorized-distributor availability outside Asia. Pacific Component Xchange specializes in sourcing hard-to-find timers and power ICs through a vetted global network, with authenticity screening and worldwide shipping. Submit an RFQ and our team will locate verified stock.
The XD555 is a request-for-quote (RFQ) item. Contact Pacific Component Xchange with your quantity and target date, and we will provide current pricing and lead time based on available inventory.
