DS1135U-8+

Overview

The DS1135U-8+ 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 with a voltage range of 4.75V to 5.25V. The device provides a nominal delay of 8ns per output tap, with an initial tolerance of ±1.0ns at nominal conditions (+25°C, VCC = +5.0V). Over the industrial temperature range (-40°C to +85°C), the tolerance extends to ±1.5ns. It features precise leading and trailing edge accuracy to preserve input symmetry and can drive up to 10 LS loads.

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

Applications

• High-speed signal timing adjustments
• Pulse width modulation circuits
• Clock distribution networks requiring precise delay matching

Procurement Notes

Verify component authenticity and datasheet revision status before integration. Confirm that the specific ordering suffix matches the required package type and RoHS compliance requirements for your manufacturing process. Ensure compatibility with existing PCB land patterns and soldering profiles.

Selection Notes

Select this component when precise, fixed delay values are required for multiple signal paths simultaneously. Compare against the DS1135L series if 3V operation is necessary instead of the standard 5V requirement. Verify that the 8-pin SOIC footprint aligns with your board design constraints.

Part Context

This device belongs to the DS1135 series, which serves as a low-power, high-speed successor to the DS1013 and DS1035 families. It is designed to replace older discrete timing solutions or legacy ICs in applications demanding compact form factors and reliable all-silicon timing performance.
