DS1135U-6+

Overview

The DS1135U-6+ 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 6ns per output with an initial tolerance of ±1.0ns at room temperature. It supports surface mount installation in an 8-pin uSOP package and functions reliably across commercial and industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Integrates three independent logic buffered delays in a single package
• Maintains stable and precise timing over temperature and voltage variations
• Preserves input symmetry through precise leading and trailing edge accuracy
• Compatible with vapor phasing, IR reflow, and wave soldering processes

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 suffix against official documentation to confirm RoHS compliance status, as indicated by manufacturer markings. Confirm current availability directly with authorized distributors or the manufacturer, as discontinuance notices may affect stock levels. Ensure the selected package type matches the required PCB footprint specifications before ordering.

Selection Notes

Select this component when three identical delay paths are required without programmability. Verify that the 6ns delay value meets the system timing requirements. Ensure the design accommodates the 8-pin uSOP package dimensions and the specified 5V power supply constraints. Check if the industrial temperature range is necessary for the target application environment.

Part Context

This device belongs to the DS1135 series of all-silicon timing circuits. It serves as a low-power, high-speed alternative to older discrete delay solutions. The series offers various fixed delay values to accommodate different timing needs while maintaining consistent performance characteristics across the family.

Replacement Considerations

Officially recommended as a replacement for the DS1013 and DS1035 models. Verify pin compatibility and electrical parameters before substitution.
