DS1044R-25+T&R

Overview

The DS1044R-25+T&R is a high-speed silicon delay line manufactured by Maxim Integrated, now part of Analog Devices Inc. This component provides a nominal delay of 25 nanoseconds with a tolerance of ±2.0 ns at nominal conditions (+25°C, VCC=+5.0V). It operates within a temperature range of 0°C to 70°C and a voltage range of 4.75 volts to 5.25 volts. The device is housed in a 14-pin SOIC package (0.154 inch width) and is supplied in tape and reel packaging for automated assembly.

Feature Summary

• Provides precise signal timing adjustment through fixed propagation delay
• Utilizes high-speed silicon technology for reliable performance
• Designed for surface-mount installation via standard SOIC footprint

Applications

• Clock distribution network synchronization
• Signal path matching in high-speed digital circuits
• Timing alignment in data acquisition systems

Procurement Notes

Verify the presence of the '+' suffix to confirm compliance with lead-free manufacturing standards as specified by the manufacturer. Ensure the '/T&R' designation matches the required tape and reel quantity for your production line. Cross-reference the full part number against official Analog Devices documentation to distinguish between bulk and reel packaging options before finalizing orders.

Selection Notes

Select this component when a fixed 25ns delay is required for timing correction in 5V logic systems. Consider the ±2.0 ns tolerance for precision applications. Evaluate the 14-pin SOIC package constraints for PCB layout. Compare against other delay values in the DS1044 family if different timing offsets are needed for specific circuit paths.

Part Context

This part belongs to the DS1044 series of 4-in-1 high-speed silicon delay lines. It shares the same functional architecture as variants like the DS1044R-10 and DS1044R-20, differing primarily in the programmed delay value. The series is designed for applications requiring multiple independent delay channels within a single compact integrated circuit package.

Replacement Considerations

Direct substitutes include other variants within the DS1044 family such as the DS1044R-10 or DS1044R-20, provided the specific delay requirement differs. Verify pin compatibility and electrical specifications before swapping. Consult official replacement guides for any updated revisions of the component.
