The Xinluda XD74LS74 is a dual D-type positive-edge-triggered flip-flop with preset and clear, a member of the long-established 74LS low-power Schottky TTL logic family. Each package contains two independent flip-flops, each with its own data (D), clock, asynchronous preset, and asynchronous clear inputs, plus complementary Q and Q-bar outputs. Data present at the D input meeting the setup-time requirement is transferred to the output on the positive-going edge of the clock pulse. A low level on the preset or clear input sets or resets the output independently of the clock. Supplied in a through-hole DIP-14 package, the XD74LS74 is well suited for prototyping, repair, and legacy production builds.
The XD74LS74 from Xinluda has limited authorized-distributor coverage, which can make it difficult to secure in production quantities or on short lead times. Pacific Component Xchange specializes in hard-to-find and discontinued logic, power-management ICs, and optocouplers. We source globally, verify authenticity, and ship worldwide so your build stays on schedule. Request a quote (RFQ) for the XD74LS74 today and our sourcing team will confirm availability, pricing, and lead time for your required quantity.
The XD74LS74 is a dual D-type positive-edge-triggered flip-flop with preset and clear, manufactured by Xinluda. It contains two independent flip-flops and belongs to the 74LS low-power Schottky TTL logic family.
The XD74LS74 is supplied in a through-hole DIP-14 package (body size 19.05 x 6.35 mm), making it convenient for prototyping, breadboarding, and repair of legacy TTL boards.
The device operates over a supply voltage range of 4.75 V to 5.25 V, consistent with standard 5 V TTL logic systems.
Per the Xinluda datasheet, the XD74LS74 has a maximum clock frequency of 25 MHz at VCC = 5 V and TA = 25 C with a 15 pF load.
The XD74LS74 follows the standard 74LS74 dual D flip-flop pinout and function, so it is generally a drop-in equivalent for other manufacturers' 74LS74 / SN74LS74A parts. Always confirm against the datasheet for your specific application.
The XD74LS74 from Xinluda has limited authorized-distributor availability. Pacific Component Xchange sources it through its global network, so pricing and lead time are confirmed per order via an RFQ.
