DS1135LZ-15/T&R

Overview

The DS1135LZ-15/T&R is a high-speed silicon delay line featuring three independent buffered delays within an 8-pin SOIC package. It operates on a single +3V supply (2.7V to 3.6V) and provides a nominal delay of 15ns per output with ±1.0ns initial tolerance at +25°C. The device maintains stable timing over temperature (-40°C to +85°C) and voltage variations, ensuring precise leading and trailing edge accuracy. It supports vapor phase and IR reflow soldering and is supplied in tape and reel format.

Feature Summary

• Three independent logic buffered delays integrated into a single low-power package
• Precise leading and trailing edge accuracy that preserves input signal symmetry
• Stable and accurate timing performance across specified temperature and voltage ranges

Applications

• Precision timing circuits requiring multiple synchronized delay paths
• Replacement for legacy DS1033 devices in existing designs
• High-speed data synchronization and pulse shaping applications

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm RoHS compliance status and packaging configuration. Confirm availability through authorized distributors as lead times may vary based on production schedules. Ensure the selected variant matches the required delay value and package type for your application design.

Selection Notes

Select this component when a low-voltage 3V operation is required alongside multiple independent delay channels. Compare the 15ns delay specification against system timing requirements to ensure it fits within the acceptable tolerance limits. Consider the 8-pin SOIC footprint constraints and verify compatibility with standard surface mount assembly processes.

Part Context

This part belongs to the DS1135L series, which serves as a low-power, 3V high-speed version of the popular DS1013, DS1033, and DS1035 series. It represents the fastest 3-in-1 delay line solution available from Maxim Integrated, offering inherent reliability through its all-silicon architecture.

Replacement Considerations

The datasheet explicitly recommends this device as a replacement for the DS1033. Verify pinout compatibility and electrical characteristics before substituting other delay lines in existing circuit designs.
