XD74LS54 – Logic Gate (AND-OR-INVERT) – Xinluda

The Xinluda XD74LS54 is a 4-wide (two 2-input and two 3-input) AND-OR-INVERT gate from the 74LS low-power Schottky TTL family, supplied in a 14-pin DIP package. Available for RFQ at Pacific Component Xchange.

The XD74LS54 from Xinluda is a 4-wide AND-OR-INVERT (AOI) logic gate belonging to the 74LS low-power Schottky TTL family. It is a pin-compatible equivalent of the industry-standard 74LS54, combining two 2-input AND gates and two 3-input AND gates into a single inverting (AND-OR-INVERT) output stage. This single-package AOI structure lets designers implement compact combinational logic such as multiplexer-style selection, sum-of-products expressions, and decode logic without cascading multiple discrete gate packages.

Built on bipolar low-power Schottky technology, the XD74LS54 offers the fast switching characteristic of the 74LS series while keeping power consumption low, making it a dependable choice for legacy board repair, education, and small-batch industrial and instrumentation designs that still rely on through-hole TTL logic.

Why Source XD74LS54 from Pacific Component Xchange

The XD74LS54 is a specialty 74LS-series logic IC with little to no authorized-distributor stock, which makes it difficult to source through conventional channels. Pacific Component Xchange specializes in hard-to-find and obsolete power-management ICs, logic, and optocouplers, helping engineers and buyers keep legacy and low-volume designs in production. We focus on authenticity and supply-chain integrity, with global shipping to keep your build on schedule. Because pricing and lead time vary with market availability, this part is offered on a request-for-quote basis. Submit an RFQ for the XD74LS54 today and our sourcing team will respond with current availability, pricing, and lead time.
