The XD74LS147 from Xinluda is a 10-line-to-4-line priority encoder built on the proven 74LS low-power Schottky TTL logic family. It encodes nine active-low data inputs into a four-line (8-4-2-1) BCD output, with priority decoding that guarantees only the highest-order active input is encoded. The implied decimal-zero condition requires no input, since zero is encoded when all nine data lines are at a high logic level. This makes the XD74LS147 a direct, pin-compatible alternative to the classic SN74LS147 for keyboard encoding, interrupt prioritization, and decimal-to-BCD conversion tasks.
The XD74LS147 is a niche 74LS-family logic device with limited authorized-distributor coverage, which can make it difficult to source in production quantities. Pacific Component Xchange specializes in hard-to-find and obsolete power-management ICs and logic components, giving engineers and buyers a reliable path to parts that mainline catalogs no longer stock in depth. Every order is backed by our authenticity and quality-assurance processes, and we ship globally to support both prototype and volume builds. Request a quote (RFQ) for the XD74LS147 today and our sourcing team will respond with current availability, lead time, and pricing.
The XD74LS147 is a 10-line-to-4-line priority encoder from Xinluda. It encodes nine active-low data inputs into a four-line (8-4-2-1) BCD output, using priority decoding so only the highest-order active input is encoded.
Yes. The XD74LS147 follows the industry-standard 74LS147 pinout and function in a DIP-16 package, making it a direct drop-in alternative to devices such as the SN74LS147 for decimal-to-BCD priority encoding.
The XD74LS147 is supplied in a 16-pin DIP (DIP-16) through-hole package and is RoHS compliant.
It operates from a 4.75 V to 5.25 V supply (nominal 5 V) over a free-air temperature range of 0 C to 70 C, with a typical propagation delay of about 18 ns.
The XD74LS147 has limited authorized-distributor availability, so Pacific Component Xchange lists it as an RFQ product. Submit a quote request and our team will confirm current stock, lead time, and pricing.
Yes. We specialize in hard-to-find and obsolete logic and power-management ICs and can source the XD74LS147 for both prototype and production quantities, with authenticity verification and global shipping.
