DS1135U-30+

Overview

The DS1135U-30+ is a high-speed, low-power silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It integrates three independent buffered delays within a single package, operating on a +5V supply voltage ranging from 4.75V to 5.25V. The device provides a nominal delay of 30ns per output with an initial tolerance of ±1.5ns at +25°C. It supports operation across commercial and industrial temperature ranges (-40°C to +85°C). The component utilizes an 8-pin SOIC (150-mil) package and features precise leading and trailing edge accuracy to preserve input symmetry.

Feature Summary

• Integrates three independent logic buffered delays in a single package
• Provides stable and precise timing over temperature and voltage variations
• Preserves input symmetry through accurate leading and trailing edge precision
• Offers inherent reliability as an all-silicon delay line solution

Applications

• Precision timing circuits requiring multiple synchronized delays
• Replacement for legacy DS1013 and DS1035 delay lines
• High-speed digital signal processing applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm RoHS compliance status, as indicated by symbols such as '+' or '-'. Confirm that the selected part number matches the required delay value and package type. Ensure compatibility with standard vapor phasing, IR, and wave soldering processes during procurement planning.

Selection Notes

Select this component when a fast 3-in-1 delay solution is required for +5V systems. Compare the 30ns delay specification against application requirements. Consider the DS1135LU series if 3V operation is necessary instead of the standard 5V configuration. Verify that the 8-pin SOIC footprint fits the design constraints.

Part Context

The DS1135 series represents a low-power, high-speed evolution of the popular DS1013 and DS1035 families. It serves as the fastest 3-in-1 delay line in its category, designed to drive up to 10 LS loads per output. The device is recommended as a direct replacement for older discrete delay solutions.

Replacement Considerations

Officially recommended as a replacement for the DS1013 and DS1035 models.
