DS1135LZ-25+

Overview

The DS1135LZ-25+ is a low-power, 3V high-speed silicon delay line featuring three independent buffered delays within an 8-pin SOIC package. It operates on a supply voltage ranging from 2.7V to 3.6V with an active current of 10mA at 3.6V. The device provides a nominal delay of 25ns per output tap, with an initial tolerance of ±1.5ns and a maximum tolerance over temperature and voltage of ±5.0ns across the -40°C to +85°C range. Output rise and fall times are typically 2.5ns, while input capacitance is 10pF.

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 signal symmetry

Applications

• Replacement for DS1033 in existing designs
• Precision timing applications requiring multiple synchronized delays
• Low-power 3V digital systems

Procurement Notes

Verify RoHS compliance status through official documentation as indicated by the suffix. Confirm package type availability and lead-free specifications directly with the manufacturer or authorized distributors. Ensure ordering details match the specific delay value and operating temperature range requirements for the intended application.

Selection Notes

Select this component when a 3V operation is required instead of the standard 5V DS1135 series. Verify that the 25ns delay meets system timing constraints. Consider the 8-pin SOIC package dimensions for PCB layout compatibility. Check if the industrial temperature range (-40°C to +85°C) aligns with environmental conditions.

Part Context

The DS1135LZ-25+ belongs to the DS1135L series, which serves as the 3V counterpart to the popular DS1013, DS1033, and DS1035 series. It is designed as a faster alternative to previous generations, offering high-speed performance in a low-power configuration suitable for modern 3V logic systems.

Replacement Considerations

Officially recommended as a replacement for the DS1033. Verify pinout compatibility and electrical characteristics before substitution.
