The Xinluda XD556 is a dual timer integrated circuit built to the industry-standard 556 architecture. It combines two independent timing circuits (functionally equivalent to two 555 timers) in a single DIP-14 package, sharing only the supply and ground pins. Each timer can be configured for either monostable (one-shot) operation to generate time delays, or astable operation as a free-running oscillator, making the XD556 a versatile building block for timing, pulse generation, and clock applications.
This part is supplied by Xinluda Information Technology Co., Ltd. and carries an End-of-Life (EOL) status, with little to no authorized-distributor stock remaining. Pacific Component Xchange supports buyers who need this obsolete component for legacy production, maintenance, and repair programs.
The XD556 is an obsolete, hard-to-find part with minimal authorized-distributor availability. As an independent distributor specializing in hard-to-find power-management ICs, timers, and optocouplers, Pacific Component Xchange helps engineers and procurement teams secure the components their designs depend on. We focus on authenticity and quality, supported by inspection and traceability processes, and we ship worldwide to keep production and service programs running.
Pricing on the XD556 is by quote. Submit an RFQ to Pacific Component Xchange with your required quantity and target date, and our sourcing team will respond with current availability and lead time for this dual timer IC.
The XD556 is a 556-type dual timer IC from Xinluda. It integrates two independent timing circuits (equivalent to two 555 timers) in a single DIP-14 package and can be used in monostable one-shot or astable oscillator configurations.
The XD556 is supplied in a 14-pin DIP (DIP-14) through-hole package, consistent with the standard 556 dual-timer pinout.
No. The XD556 is marked End-of-Life (EOL) / obsolete by Xinluda, and authorized-distributor availability is very limited. Pacific Component Xchange sources this part on a request-for-quote basis.
The XD556 follows the industry-standard 556 dual-timer architecture and DIP-14 pinout, making it functionally a member of the 556 / NE556 / LM556 family. Always confirm exact electrical parameters against the manufacturer datasheet for your application.
The XD556 is specified for a commercial operating temperature range of 0u00b0C to +70u00b0C.
Submit a Request for Quote (RFQ) with your required quantity and delivery date. Because the XD556 is obsolete and hard to find, pricing and lead time are provided by quote, and our sourcing team will confirm current availability.
