DS1135LU-20+

Overview

The DS1135LU-20+ is a low-power, 3V high-speed silicon delay line from the DS1135L series. It integrates three independent logic buffered delays within a single package. The device operates on a +3V supply with a voltage range of 2.7V to 3.6V and functions across an industrial temperature range of -40°C to +85°C. It provides a nominal delay of 20ns per output tap with specific tolerance limits over temperature and voltage variations.

Feature Summary

• All-silicon timing circuit providing inherent reliability
• Three independent buffered delay channels in one package
• Stable and precise performance over temperature and voltage changes
• Leading and trailing edge precision preserves input symmetry

Applications

• Timing synchronization in digital systems
• Signal path delay compensation
• Replacement for legacy DS1033 delay lines

Procurement Notes

Verify the ordering suffix matches the required package type and RoHS compliance status. Confirm that the specified delay value aligns with system timing requirements. Check for availability constraints as distribution may vary by region. Ensure the component meets environmental specifications for the intended operating temperature range.

Selection Notes

Select this component when a compact solution for multiple synchronized delays is required. The 3V operation makes it suitable for low-voltage applications. Consider the 20ns delay value against system clock speeds. Verify compatibility with existing logic levels and power supply rails before integration into the design.

Part Context

The DS1135LU-20+ belongs to the DS1135L family of high-speed silicon delay lines. This series serves as a modern replacement for older discrete timing components like the DS1033. The device consolidates three delay functions into a small footprint, simplifying board layout compared to using separate timing elements.
