74HC74

The 74HC74 is a high-speed CMOS dual D-type positive-edge-triggered flip-flop integrated circuit. Commonly used in digital electronics for memory storage, frequency division, and shift registers, it contains two independent flip-flops, each with Data (D), Clock (CP), Set (Preset), Reset (Clear), and complementary Q and Q̄ outputs.
