XD74LS51 – Logic Gate (AND-OR-INVERT) – Xinluda

The Xinluda XD74LS51 is a 74LS-series TTL dual 2-wide 2-input AND-OR-INVERT logic gate in a through-hole DIP-14 package, operating from a 5V supply. Available now for RFQ from Pacific Component Xchange.

The XD74LS51 from Xinluda is a member of the classic 74LS family of low-power Schottky TTL logic and implements the AND-OR-INVERT (AOI) gate function. As part of the 7451/74LS51 lineage, it provides dual 2-wide 2-input AND-OR-INVERT gating in a compact through-hole DIP-14 package, making it a reliable, drop-in choice for digital designs that need combinational AOI logic from a standard 5V rail.

The XD74LS51 is well suited to maintenance, repair, and legacy production builds where a verified 74LS51-compatible part is required. Pacific Component Xchange stocks and sources this Xinluda device for customers who cannot find it through mainstream authorized channels.
