25LS2518FM/B

Overview

The 25LS2518FM/B is a quad D-type flip-flop register manufactured by Rochester Electronics, LLC. This component provides four independent D-type storage elements within a single package, designed for high-speed digital data retention and transfer applications. It features dedicated clock inputs to synchronize data capture across all quadrants simultaneously. The device supports standard logic voltage levels suitable for legacy system integration. It is housed in a plastic DIP package configuration, ensuring compatibility with through-hole mounting techniques commonly found in industrial and commercial electronic equipment.

Feature Summary

• Quad D-type flip-flop architecture for multi-bit data storage
• Synchronized clock input for simultaneous data latching
• Plastic dual in-line package for reliable through-hole integration

Applications

• Digital data register circuits
• Shift register implementations
• Memory buffer stages in control systems

Procurement Notes

Verify the specific manufacturer source when ordering, as Rochester Electronics specializes in sustaining obsolete components. Confirm that the received unit matches the exact part number designation to ensure functional integrity. Request original documentation or test reports if available to validate authenticity. Check for any suffix variations that may indicate different packaging or testing standards. Ensure compliance with relevant quality management certifications provided by the supplier.

Selection Notes

Select this component when a quad D-type flip-flop is required for legacy system maintenance or replacement of discontinued parts. Consider the package type and pinout compatibility with existing board layouts. Evaluate the operating temperature range against environmental conditions. Verify signal integrity requirements match the device specifications. Assess supply chain reliability given the specialized nature of lifecycle support components.

Part Context

Rochester Electronics focuses on sustaining production of mature semiconductor technologies rather than developing new ones. The 25LS2518FM/B represents their capability to maintain inventory of critical logic devices. This approach supports industries requiring long-term availability of specific integrated circuits. The company operates as an authorized source for these sustained products, bridging the gap between original manufacturers and end-users needing continued supply.

Replacement Considerations

Direct substitutes include other quad D-type flip-flops with identical pinouts and logical functions. Verify electrical characteristics such as propagation delay and power consumption before substitution. Ensure mechanical dimensions match the original footprint for seamless installation.
