The MC74F174N is a Hex D-type flip-flop with a common clear input manufactured by Freescale Semiconductor (now NXP). This device belongs to the 74F family, known for its high-speed operation. It contains six independent D-type flip-flops that share a common clear input. Data at the D input is transferred to the Q output on the rising edge of the clock pulse.

Applications

• Data Storage: Stores data in digital systems.
• Register Files: Used as building blocks for register files.
• Buffer Registers: Provides temporary storage of data.
• Control Registers: Stores control signals in digital systems.
• Digital Instrumentation: Used in digital instruments for data acquisition and control.

Features

• Hex D-Type Flip-Flops: Contains six independent D-type flip-flops.
• Common Clear Input: Clears all flip-flops simultaneously.
• Rising-Edge Triggered: Data is transferred on the rising edge of the clock.
• High-Speed Operation: Offers fast switching speeds typical of the 74F family.
• TTL Compatible: Compatible with standard TTL logic levels.

Benefits

• Efficient Data Storage: Provides a convenient way to store multiple bits of data.
• Simplified Design: Reduces component count compared to discrete flip-flop implementations.
• High Performance: Fast switching speeds enable high-speed system operation.
• Easy Integration: TTL compatibility simplifies integration with other logic devices.
• Versatile Functionality: Can be used in a variety of data storage and control applications.

Additional Details

The MC74F174N is typically available in a DIP (Dual In-Line Package). The clear input asynchronously resets all flip-flops to zero. The data at the D input is transferred to the Q output on the rising edge of the clock pulse only if the clear input is inactive (high). Understanding the timing requirements of the clock and data inputs is crucial for proper operation in flip-flop applications.
