Product Description

The SN74HC74DBRG4 features two independent D-type flip-flops with direct clear and preset inputs. Each flip-flop has individual clear and set inputs, along with a common clock input. The device changes state on the positive going transition of the clock pulse if the clear input is not asserted. If the clear input is asserted during the clock pulse, the Q output is set low and the Q̅ output is set high.

Constructed with silicon-gate CMOS technology, it assures a reliable operation with low power consumption. The SN74HC74DBRG4 also provides a balanced propagation delay and transition times, which is essential for synchronous operations in digital systems. The device is compatible with TTL logic levels and can drive up to 10 LSTTL loads.

Available in a small-outline package, the SN74HC74DBRG4 is optimized for improved PCB space efficiency and is suitable for automated surface-mount processes. With its robust design and versatility, this flip-flop is an excellent choice for designers looking to implement reliable flip-flop logic in their digital circuits.
