IC 7474 Dual D-Type Flip-Flop

IC 7474 Dual D-Type Flip-Flop

The IC 7474 is a digital logic integrated circuit that contains two independent D-type (Data) flip-flops with preset and clear inputs. It is part of the 74xx TTL family and is widely used for data storage, timing, and sequential logic operations.

Each flip-flop captures the input data on the rising edge of the clock signal, making it ideal for synchronization and memory applications in digital circuits.
