DS1135LU-30+

Overview

The DS1135LU-30+ is a low-power, 3V high-speed silicon delay line featuring three independent buffered delays in an 8-pin uSOP package. It operates on a supply voltage of 2.7V to 3.6V with an active current of 10mA at 3.6V. The device provides a nominal delay of 30ns per output, with initial tolerances of ±1.5ns and temperature/voltage drifts up to ±5.0ns across the -40°C to +85°C range. Output rise/fall times are typically 2.5ns, and input capacitance is 10pF.

Feature Summary

• All-silicon timing circuit providing inherent reliability
• Three independent logic buffered delays in a single package
• Precise leading and trailing edge accuracy preserving input symmetry
• Stable and precise performance over temperature and voltage variations

Applications

• Timing circuits requiring multiple synchronized delays
• Replacement for legacy DS1033 devices
• High-speed digital signal processing applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Ensure ordering suffixes match specific package requirements. Check for end-of-life notifications before finalizing procurement plans.

Selection Notes

Select this model when three identical delay paths are required within a compact surface-mount footprint. Verify that the 30ns delay value aligns with system timing constraints. Ensure the operating voltage range matches the 2.7V to 3.6V specification. Consider thermal dissipation limits if operating near maximum ambient temperatures.

Part Context

Part of the DS1135L series designed as a 3V high-speed alternative to older DS1013 and DS1035 families. Manufactured by Analog Devices / Maxim Integrated. Available in lead-free/RoHS-compliant packaging indicated by the '+' suffix. Designed for commercial and industrial temperature ranges.

Replacement Considerations

Officially recommended as a replacement for the DS1033. Verify pin compatibility and electrical characteristics against existing designs. Ensure the new delay values meet system timing requirements.
