Présentation

Description

The 74HC74BQ is a high-speed CMOS dual D-type flip-flop featuring two edge-triggered flip-flops in a single package. It belongs to the 74HC series, known for its high-speed logic capabilities and low power consumption. Each flip-flop has an independent data (D) input, clock (CP) input, set (SD) input, reset (RD) input, and outputs (Q and Q̅).
The device operates with a supply voltage range of 2V to 6V and is compatible with TTL voltage levels. The 74HC74BQ is used for storing binary data and is triggered on the low-to-high transition of the clock input. The asynchronous set and reset inputs allow for immediate setting or clearing of the flip-flops, regardless of the clock input state.
Common applications include data storage, shift registers, and binary counters in digital circuits. It is suitable for use in consumer electronics, computing devices, and communication equipment, thanks to its reliable performance and ease of integration into various digital systems.
