DS1135LU-15/T&R

Overview

The DS1135LU-15/T&R is a low-power, 3V high-speed silicon delay line from the DS1135L series. It integrates three independent buffered delays in an 8-pin SOIC package. The nominal delay per output is 15ns with an initial tolerance of ±1.0ns at +25°C and VCC = +3.3V. Over the industrial temperature range (-40°C to +85°C) and voltage range (2.7V to 3.6V), the tolerance is specified as ±4.0ns. The device operates on a single supply voltage between 2.7V and 3.6V, drawing a typical active current of 10mA.

Feature Summary

• Three independent logic buffered delays integrated into a single package
• Precise leading and trailing edge accuracy that preserves input symmetry
• Stable and precise timing performance over temperature and voltage variations
• Compatible with vapor phase and IR reflow soldering processes

Applications

• Replacement for the DS1033 delay line
• Precision timing circuits requiring multiple synchronized delays
• High-speed signal processing applications

Procurement Notes

Verify the specific suffix '/T&R' indicates tape and reel packaging when sourcing this component. Confirm RoHS compliance status based on the '+' designation if required by assembly specifications. Check for discontinuance notices or limited availability as older Maxim Integrated products may have restricted supply chains.

Selection Notes

Select the DS1135LU-15/T&R when a 15ns delay value is required within the 3V family. Ensure the application supports the 8-pin SOIC footprint. Compare against other DS1135L variants if different delay values like 10ns or 20ns are needed. Verify power consumption requirements align with the 10mA active current specification.

Part Context

This component belongs to the DS1135L series, which serves as a low-power, 3V version of the earlier DS1013, DS1033, and DS1035 series. The series provides all-silicon timing solutions with inherent reliability. The 'LU' designation typically refers to the uSOP package variant, though datasheet revisions indicate package options may vary.

Replacement Considerations

The datasheet explicitly recommends the DS1135L series as a replacement for the DS1033. When substituting, verify pin compatibility and ensure the new part meets the required delay tolerance and operating voltage ranges.
