DS1135LU-10

Overview

The DS1135LU-10 is a low-power, 3V high-speed silicon delay line featuring three independent buffered delays within an 8-pin SO package. It operates on a supply voltage ranging from 2.7V to 3.6V with an active current of 10mA at maximum voltage. The device provides a nominal delay of 10ns per output, with an initial tolerance of ±1.0ns and a total tolerance over temperature and voltage of ±3.0ns across the industrial range of -40°C to +85°C. Output rise and fall times are typically 2.5ns.

Feature Summary

• All-silicon timing circuit providing stable and precise delays over temperature and voltage variations
• Three independent logic buffered delays in a single package for compact design
• Leading and trailing edge precision preserves input symmetry

Applications

• Precision timing circuits requiring multiple synchronized delays
• Replacement for legacy DS1033 series components
• Industrial applications requiring operation across commercial and industrial temperature ranges

Procurement Notes

Verify RoHS compliance status by checking for the '+' suffix in the part number, as indicated in the ordering information. Confirm package type availability, noting that datasheet revisions may update standard offerings. Ensure sourcing channels provide valid documentation matching the specific revision history for accurate parameter verification.

Selection Notes

Select this component when a 3V supply is required instead of the 5V variants like the DS1135U. Verify that the 10ns delay meets system requirements, as other values such as 12ns or 15ns are available in the same series. Ensure the 8-pin SO package fits the PCB layout constraints compared to older µSOP options.

Part Context

The DS1135L series serves as a low-power, 3V high-speed version of the popular DS1013, DS1033, and DS1035 series. It is designed as the fastest 3-in-1 delay line solution, offering inherent reliability through its all-silicon architecture while maintaining precise timing characteristics.

Replacement Considerations

The datasheet explicitly recommends the DS1135L series as a replacement for the DS1033 U10. When substituting, verify the supply voltage difference between the 3V DS1135L and the 5V DS1033 to ensure compatibility with existing power rails.
