Product Description

The SN74HCT74APWR features two independent D-type flip-flops with direct clear and preset inputs. It is characterized for operation from -40°C to 85°C, ensuring reliable performance in a wide range of environmental conditions. The device also provides a standard pinout, which is compatible with other standard logic families, making it easy to use in mixed-logic environments.

Each flip-flop has individual clear and set inputs, as well as a clock input. The outputs can drive up to 10 LSTTL loads, which makes the device suitable for a variety of digital applications. The flip-flops are positive-edge triggered, meaning that the data on the D input is accepted and transferred to the Q output on the rising edge of the clock pulse. The clear and preset inputs are asynchronous, which means that the flip-flop can be set or reset at any time, regardless of the clock input.

Applications

The SN74HCT74APWR is ideal for use in a variety of applications, including:

• Registers
• Counters
• Control circuits
• Memory storage elements
• System clocks

With its robust design and versatile functionality, the SN74HCT74APWR is a reliable choice for designers looking for a dual D-type flip-flop that can meet the demands of complex digital systems.
