DS1135LZ-25+T&R

Overview

The DS1135LZ-25+T&R is a low-power, 3V high-speed silicon delay line from the DS1135L series. It integrates three independent logic buffered delays in an 8-pin SOIC (150-mil) package. The device provides a nominal delay of 25ns per output with an initial tolerance of ±1.5ns at +25°C and VCC = +3.3V. Operating voltage ranges from 2.7V to 3.6V, with an active current of 10mA at 3.6V. It supports industrial temperature operation from -40°C to +85V and features precise leading and trailing edge accuracy.

Feature Summary

• Three independent buffered delay channels within a single package
• Stable and precise timing performance over temperature and voltage variations
• Preserves input symmetry through accurate leading and trailing edge precision
• Compatible with vapor phase, IR reflow, and wave soldering processes

Applications

• Precision timing circuits requiring multiple synchronized delays
• Replacement for legacy DS1033 devices
• Low-power digital signal processing applications

Procurement Notes

Verify RoHS compliance status indicated by the '+' suffix. Confirm tape and reel packaging availability for automated assembly. Check lead time constraints as this component may be subject to limited supply conditions. Ensure ordering matches the specific 25ns delay requirement.

Selection Notes

Select this part for 3V applications requiring three identical delay paths. Compare against DS1135LZ-20+ or DS1135LZ-30+ if different delay values are needed. Verify that the 150-mil SOIC footprint fits the design constraints. Consider the DS1135Z series if 5V operation is required instead of 3V.

Part Context

This component belongs to the DS1135L family of 3V high-speed silicon delay lines. It serves as a modern replacement for older Dallas Semiconductor parts like the DS1033. The 'Z' indicates the 150-mil SOIC package, while '+T&R' denotes lead-free/RoHS-compliant tape and reel packaging.

Replacement Considerations

DS1033 is listed as a recommended replacement target. No direct cross-model substitutes are documented in the provided datasheet.
