The 54LS174DMQB is a high-speed Hex D Flip-Flop with a common clear input, manufactured by Fairchild/ON Semiconductor. This device consists of six edge-triggered D-type flip-flops. The flip-flops will store the logic states that were set up at their respective D inputs. These inputs are sampled during the clock's positive transition. A high signal applied to the clear input will clear all six flip-flops.

Applications:

• Registers
• Counters
• Control Circuits
• Memory Storage Units
• Data Buffering

Features:

• High-Speed Operation: Ideal for applications where speed is critical.
• Edge-Triggered D-Type Flip-Flops: Ensures reliable data storage based on the clock's positive edge.
• Common Clear Input: Allows for simultaneous clearing of all six flip-flops.
• TTL (Transistor-Transistor Logic) Compatibility: Ensures easy interfacing with other TTL logic devices.
• Military Temperature Range: Operates reliably over a wide temperature range (-55°C to +125°C).
• Ceramic DIP Package: Provides robust protection and ease of installation.

Benefits:

• Simplified System Design: The hex configuration minimizes the number of ICs needed, reducing board space and complexity.
• Reliable Data Storage: Edge-triggering ensures accurate data capture.
• Easy Initialization: The common clear input simplifies system reset operations.
• Wide Operating Temperature: Suitable for use in harsh environments.
• Improved System Performance: High-speed operation allows for faster data processing.
