The Xinluda XD74LS166 is an 8-bit shift register from the industry-standard 74LS (Low-power Schottky TTL) logic family. It is configured as a parallel-input or serial-input, serial-output device, allowing eight bits of data to be loaded in parallel and then clocked out serially, one bit at a time. This makes it a versatile building block for serializing data, bus expansion, and digital data handling in legacy and cost-sensitive designs.
The device features a gated clock input and an overriding asynchronous clear, with a shift/load control input that selects between synchronous parallel loading and serial shifting. The XD74LS166 follows the well-established JEDEC 74LS166 function and pinout, making it a drop-in functional equivalent for the standard 74LS166/SN74LS166 used across decades of TTL designs.
The XD74LS166 is a specialty Xinluda-branded logic IC with limited authorized-distributor coverage in Western markets, which can make it difficult to source through mainstream channels. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs and logic components. We help engineers and buyers secure parts like the XD74LS166 when standard supply chains come up short.
Every order is backed by our commitment to authenticity and quality, with inspection and traceability support, plus global shipping to keep your production and repair schedules on track. Because this is a Request-For-Quote item, pricing and lead time are confirmed per inquiry based on current sourcing. Submit an RFQ today and our sourcing team will respond with availability, pricing, and lead-time for the quantity you need.
The XD74LS166 is an 8-bit parallel-in/serial-out shift register from Xinluda, supplied in a DIP-16 package. It belongs to the standard 74LS Low-power Schottky TTL logic family and follows the JEDEC 74LS166 function and pinout.
Yes. The XD74LS166 follows the standard 74LS166 JEDEC function and pinout, making it a functional equivalent to the SN74LS166 and other 74LS166 devices from manufacturers such as Texas Instruments, Fairchild, and Motorola.
Xinluda supplies the XD74LS166 in a 16-pin dual in-line package (DIP-16), a through-hole format suited to legacy boards, repairs, and prototyping.
Per the Xinluda datasheet, the XD74LS166 operates over the commercial temperature range of 0u00b0C to +70u00b0C.
The XD74LS166 is a Xinluda-branded part with limited authorized-distributor coverage outside of Asia. Pacific Component Xchange specializes in sourcing these hard-to-find logic ICs through independent supply channels.
