The DM74S174 is a Hex D-Type Flip-Flop with Clear from Fairchild Semiconductor (now ON Semiconductor). This device contains six independent D-type flip-flops that can store binary data. The common clear input allows for resetting all flip-flops simultaneously.

Applications

• Data storage: Used for storing binary data in digital systems.
• Registers: Can be used to build shift registers, storage registers, and other register-based circuits.
• Counters: Employed in synchronous counter designs.
• Memory systems: Used as building blocks for small memory arrays.
• Digital delay lines: Creates time delays in digital signals.

Features

• Hex D-type flip-flops: Contains six independent D-type flip-flops in a single package.
• Common clear input: Allows for synchronous resetting of all flip-flops.
• High speed: Utilizes Schottky TTL technology for fast switching speeds.
• Clock enable: Data is transferred to the output on the positive edge of the clock pulse.
• High fan-out: Can drive a large number of other logic gates.

Benefits

• High-speed operation: Schottky TTL technology enables fast data processing.
• Simplified system design: Common clear input simplifies resetting all flip-flops simultaneously.
• Increased data storage capacity: Provides six independent storage elements in a single package.
• Versatile functionality: Can be used in a wide variety of digital logic applications.
• Improved system performance: High fan-out allows for driving multiple loads without signal degradation.

Additional Details

The DM74S174 operates from a single 5V power supply. It is typically available in a 16-pin DIP (Dual In-line Package). Data is transferred from the D input to the Q output on the positive-going edge of the clock pulse. The clear input, when low, resets all flip-flops to a low state, regardless of the clock or data inputs. The Schottky TTL technology ensures fast switching speeds, making it suitable for high-performance digital systems. It is commonly used in applications requiring synchronous data storage and manipulation.
