DS1044R-7

Overview

The DS1044R-7 is a high-speed silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It integrates four independent logic buffered delays within a single package, serving as a compact timing solution. The device operates on a +5 Volt supply and utilizes all-silicon technology for precise timing control. It features an initial delay tolerance of ±1.5 ns and maintains stability over temperature and voltage variations. The component preserves input symmetry through leading and trailing edge precision. It is housed in a standard 14-pin SOIC package suitable for surface mount applications.

Feature Summary

• Integrates four independent buffered delay lines in a single package
• Provides stable and precise timing performance across temperature and voltage ranges
• Preserves input signal symmetry via leading and trailing edge precision

Applications

• High-speed digital timing circuits
• Signal synchronization systems
• Precision clock distribution networks

Procurement Notes

Verify the specific suffix 'R-7' against official datasheets to confirm tape and reel packaging status. Confirm current lifecycle status as components from this series may be discontinued or subject to last-time buy notices. Ensure compatibility with existing 14-pin SOIC footprints during procurement planning.

Selection Notes

Select this component when multiple independent delay channels are required in a space-constrained design. Consider the ±1.5 ns initial tolerance for applications requiring moderate precision. Verify that the +5V operating voltage aligns with the system power rails. Evaluate the 14-pin SOIC package size against available board real estate.

Part Context

The DS1044 series represents a 4-in-1 version of the DS1035 delay line family. Originally developed by Dallas Semiconductor before its acquisition by Maxim Integrated, these devices offer high-speed performance in a low-power format. The R-7 variant specifically denotes the SOIC package configuration with associated packaging specifications.

Replacement Considerations

Check for direct pin-compatible replacements within the DS1044 family. Verify if newer generation delay lines from Analog Devices offer improved tolerance or lower power consumption while maintaining the 14-pin SOIC form factor.
