DS1135U-15+

Delay Lines IC Overview

The DS1135U-15+ is a high-speed 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 15ns per output with an initial tolerance of ±1.5ns at +25°C and VCC = +5.0V. Over the industrial temperature range of -40°C to +85°C, the tolerance extends to ±2ns. It utilizes an 8-pin SOIC (150-mil) package and features precise leading and trailing edge accuracy to preserve input symmetry.

Delay Lines IC 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 precise leading and trailing edge accuracy
• Offers inherent reliability as an all-silicon delay line solution

Delay Lines IC Applications

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

Delay Lines IC Procurement Notes

Verify component authenticity upon receipt, as the market contains counterfeit integrated circuits. Confirm the RoHS compliance status indicated by the '+' suffix matches project requirements. Ensure the 8-pin SOIC footprint aligns with existing PCB land patterns. Check for any specific handling precautions related to static sensitivity during assembly.

Delay Lines IC Selection Notes

Select this component when three identical delay paths are required without programmability. Compare against the DS1135L series if 3V operation is necessary instead of the standard 5V supply. Verify that the 15ns delay value meets system timing constraints. Consider the 8-pin SOIC package size relative to available board space compared to other packages like uSOP or DIP.

Delay Lines IC Part Context

The DS1135 series represents a low-power, high-speed evolution of the popular DS1013 and DS1035 devices. It serves as the fastest 3-in-1 delay line in its family, designed for applications demanding precise timing control. The device maintains compatibility with standard soldering processes including vapor phasing, IR, and wave soldering.
