XD74LS76 – Dual JK Flip-Flop – Xinluda
The XD74LS76 from Xinluda is a dual negative-edge-triggered JK flip-flop with preset and clear in a DIP-16 package, part of the 74LS low-power Schottky logic family. Available for RFQ through Pacific Component Xchange.
The XD74LS76 is a dual J-K flip-flop manufactured by Xinluda Information Technology Co., Ltd., built around the proven 74LS (low-power Schottky) logic architecture. It integrates two independent negative-edge-triggered J-K flip-flops, each with its own asynchronous preset and clear inputs, making it a versatile building block for sequential logic, counters, and state machines. The device is supplied in a through-hole DIP-16 package, ideal for prototyping, legacy board repair, and educational designs.
