The 54F174DMQB is a high-speed hex D-type flip-flop from Texas Instruments (formerly National Semiconductor), designed for use in high-performance synchronous systems. Its key feature is the ability to store six bits of data simultaneously, making it ideal for applications requiring parallel data handling, specifically within environments demanding high reliability and stringent performance standards.

Applications

• Military and Aerospace systems: Used in critical control and data processing systems that demand high reliability.
• High-speed registers: Ideal for use as temporary storage in high-speed processing units.
• Data buffering: Provides buffering between different parts of a digital system operating at different speeds.
• Address latching: Used to latch address information in memory systems.
• Control registers: For storing control signals in complex digital systems.

Features

• Hex D-Type Flip-Flops: Contains six independent D-type flip-flops in a single package.
• Common Clear Input: All flip-flops can be simultaneously cleared via a common clear input.
• Positive-Edge Triggered Clocking: Data is latched on the rising edge of the clock signal.
• High-Speed Operation: Fast propagation delays enable use in high-frequency systems.
• Military Temperature Range: Operates reliably over the full military temperature range (-55°C to +125°C).

Benefits

• Parallel Data Handling: Efficiently stores and retrieves multiple bits of data simultaneously.
• Synchronous Operation: Simplifies timing design in synchronous digital systems.
• High Reliability: Designed and manufactured to meet stringent military specifications.
• Simplified System Design: Reduces component count and board space compared to using discrete flip-flops.
• Enhanced System Performance: High-speed operation minimizes delays and maximizes throughput.

The 54F174DMQB is typically packaged in a ceramic dual-in-line package (DIP) or flatpack, which offers excellent thermal and mechanical stability. It operates from a 5V power supply and provides TTL compatible inputs and outputs. The device is specifically designed to meet the requirements of MIL-STD-883, ensuring high reliability and performance in harsh environments. Its robust design and high-speed capabilities make it a preferred choice for critical applications in military and aerospace systems where performance and reliability are paramount.
