DS1135LZ-25

Overview

The DS1135LZ-25 is a high-speed silicon delay line featuring three independent buffered delays in an 8-pin SOIC package. It operates on a single +3V supply with a voltage range of 2.7V to 3.6V and functions within a temperature range of -40°C to +85°C. The nominal delay per output is 25ns, with an initial tolerance of ±1.5ns at +25°C. Over the industrial temperature range, the tolerance extends to ±5.0ns. The device provides precise leading and trailing edge accuracy to preserve input symmetry.

Feature Summary

• Three independent logic buffered delays integrated into a single package
• Stable and precise timing performance over temperature and voltage variations
• High precision on both leading and trailing edges maintains input signal symmetry

Applications

• Replacement for legacy DS1033 delay lines
• Precision timing circuits requiring multiple synchronized delays
• Systems utilizing standard fundamental mode crystals or clock inputs

Procurement Notes

Verify RoHS compliance status by checking for the '+' suffix in the ordering code, as indicated in official documentation. Confirm that the specific package variant matches the required footprint, noting that older datasheets may reference obsolete packages like uSOP which are no longer supported in current revisions.

Selection Notes

Select this component when a low-power, 3V operation is required alongside multiple delay taps. Ensure the application can accommodate the specified 25ns delay value and its associated tolerances across the intended operating temperature range. Verify that the 8-pin SOIC package dimensions fit the available board space constraints.

Part Context

This part belongs to the DS1135L series, representing a low-power, 3V high-speed evolution of the earlier DS1013, DS1033, and DS1035 families. It serves as a direct functional replacement for these legacy parts while offering improved power efficiency and modern packaging options suitable for surface mount assembly.

Replacement Considerations

Officially recommended as a replacement for the DS1033. Verify pin compatibility and ensure the new 3V supply rail meets the absolute maximum ratings of the existing circuit design before implementation.
