The TC74AC74FN is a Dual D-Type Flip-Flop with Set and Reset manufactured by Toshiba Semiconductor and Storage. It belongs to the Advanced CMOS (AC) logic family, offering high-speed performance and low power consumption. The device consists of two independent D-type flip-flops within a single package. The 'FN' suffix usually denotes a specific package type. Each flip-flop has individual set and reset inputs, providing asynchronous control over the output state.

Applications:

• Shift registers
• Data synchronization
• Control circuits
• Frequency dividers
• Memory storage elements

Features:

• High-speed operation: tpd = 7.5 ns (typ.) at VCC = 5 V
• Low power consumption: ICC = 4 μA (max.) at VCC = 5 V
• Dual D-type flip-flop configuration
• Set and Reset inputs for asynchronous control
• Positive-edge triggered operation
• Wide operating voltage range: VCC = 2 V to 6 V
• Operating temperature range: -40°C to 85°C (Typical, confirm with datasheet)

Benefits:

• Reliable Data Storage: Provides reliable data storage in digital systems.
• Asynchronous Control: Set and Reset inputs allow for direct and immediate control over the flip-flop's output.
• High-Speed Performance: Enables rapid data transfer and processing.
• Reduced Power Consumption: Low power consumption makes it suitable for battery-powered and energy-sensitive applications.
• Versatile Application: Suitable for a variety of data storage and control applications.

Additional Details:

The TC74AC74FN typically comes in a SOIC (Small Outline Integrated Circuit) package for surface mount assembly on PCBs. Data is clocked into the flip-flop on the positive-going edge of the clock (CLK) input. The Set and Reset inputs override the clock and data inputs, allowing for direct setting or clearing of the flip-flop's output. When Set is low, the Q output goes high. When Reset is low, the Q output goes low. Avoid applying both Set and Reset simultaneously, as this results in an undefined output state.
