XD74LS112 – Dual J-K Flip-Flop – Xinluda

The Xinluda XD74LS112 is a dual J-K negative-edge-triggered flip-flop with individual preset and clear inputs, supplied in a 16-pin DIP package. Part of the classic 74LS TTL logic family, it is available for RFQ from Pacific Component Xchange.

The XD74LS112 from Xinluda is a dual J-K negative-edge-triggered flip-flop with preset and clear, built on the long-established 74LS (low-power Schottky TTL) logic family. Each device integrates two independent flip-flops, each with its own J, K, clock, asynchronous preset (set), and clear inputs plus complementary Q and Q-bar outputs. Data present at the J and K inputs is transferred to the outputs on the negative (falling) edge of the clock pulse, making the XD74LS112 a reliable building block for counters, frequency dividers, shift registers, and general sequential logic.

Supplied in a through-hole 16-pin DIP package, the XD74LS112 is a drop-in functional equivalent to industry-standard 74LS112 devices and interfaces directly with TTL, NMOS, and CMOS logic levels.
