XD74LS74
by XINLUDA(信路达)Clocked state storage is the main role of XINLUDA's XD74LS74, a dual D-type flip-flop in the 74LS logic family. It is useful for registering digital signals and building sequential logic, with preset and clear controls providing asynchronous control of stored state. The through-hole DIP-14 implementation has 14 symbol pins and a matching count of 14 footprint pads. Its free KiCad files contain the symbol, DIP-14_L19.4-W6.4-P2.54-LS7.6-BL footprint and included 3D model. Verification consisted of converting a real ProtoFlow import and checking the result in the editor. This flip-flop can be opened directly in ProtoFlow.
