DS1135U-25+W

Overview

The DS1135U-25+W is a high-speed silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It integrates three independent logic buffered delays within a single package, functioning as a 3-in-1 timing circuit. The device operates on a +5V supply with a voltage range of 4.75V to 5.25V. It utilizes an 8-pin uSOP surface-mount package and supports commercial and industrial temperature ranges from -40°C to +85°C. This component serves as a recommended replacement for legacy parts like the DS1013 and DS1035.

Feature Summary

• Integrates three independent buffered delay lines in a compact package
• Maintains stable and precise timing performance across temperature and voltage variations
• Preserves input symmetry through leading and trailing edge precision

Applications

• Precision timing circuits requiring multiple delay stages
• Replacement for DS1013 and DS1035 in existing designs
• High-speed signal processing applications

Procurement Notes

Verify RoHS compliance status carefully, as historical data indicates mixed availability between compliant and non-compliant variants for this series. Confirm the specific suffix designation with the manufacturer or authorized distributors to ensure environmental regulation adherence. Check current lifecycle status as some units may be discontinued or subject to limited supply constraints.

Selection Notes

Select this variant when three independent delay channels are required in a small form factor. Ensure the design accommodates the 4.75V to 5.25V operating voltage range. Consider the 8-pin uSOP package dimensions for PCB layout. Verify thermal requirements against the -40°C to +85°C operational range.

Part Context

This component belongs to the DS1135 series, which represents a low-power, high-speed evolution of earlier Dallas Semiconductor delay lines. The series is designed to offer superior speed and integration compared to predecessors. The 'U' suffix typically denotes the uSOP package type, while '+W' often indicates lead-free/RoHS compliance in Maxim's nomenclature.

Replacement Considerations

Officially recommended as a direct replacement for the DS1013 and DS1035 models. Designers migrating from these legacy parts should verify pin compatibility and electrical characteristics to ensure seamless integration without circuit modification.
