DS1135LU-12+

Overview

The DS1135LU-12+ is a 3V high-speed silicon delay line featuring three independent buffered delays in an 8-pin uSOP package. It operates within a supply voltage range of 2.7V to 3.6V and supports an industrial temperature range from -40°C to +85°C. The device provides a nominal delay of 12ns per output with an initial tolerance of ±1.0ns at 25°C. Over the full operating temperature and voltage range, the delay tolerance is specified as ±3.0ns. It draws a typical active current of 10mA at 3.6V.

Feature Summary

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

Applications

• Replacement for the DS1033 delay line series
• Low-power 3V system timing applications
• High-speed digital signal processing synchronization

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for end-of-life notifications or discontinuance alerts prior to procurement planning. Ensure storage conditions adhere to specified limits to maintain reliability.

Selection Notes

Select this component when a low-voltage 3V operation is required alongside precise timing control. Compare against the standard 5V DS1135Z series if power consumption is a critical constraint. Verify that the 8-pin uSOP footprint fits the target PCB layout constraints. Ensure the 12ns delay value aligns with the specific timing requirements of the application design.

Part Context

This part belongs to the DS1135L series, which serves as the low-power, 3V variant of the popular DS1013, DS1033, and DS1035 families. It is designed as a faster alternative within the 3-in-1 delay line category, offering all-silicon reliability in a small surface-mount package suitable for modern electronic designs.

Replacement Considerations

Officially recommended as a replacement for the DS1033. Designers should verify pin compatibility and electrical characteristics against legacy components before substitution.
