DS1135U-6+T&R

Overview

The DS1135U-6+T&R is a high-speed silicon delay line featuring three independent buffered delays within an 8-pin uSOP package. It operates on a single +5V supply (4.75V to 5.25V) and provides a nominal delay of 6ns per output with an initial tolerance of ±1.0ns at +25°C. The device maintains stable timing over the -40°C to +85°C industrial temperature range, with voltage-dependent tolerance reaching ±1.5ns. Each output can drive up to 10 LS loads, ensuring reliable signal integrity in complex timing applications.

Feature Summary

• Integrates three independent logic buffered delays in a single compact package
• Maintains precise leading and trailing edge accuracy to preserve input symmetry
• Provides inherent reliability through an all-silicon timing circuit solution

Applications

• Precision clock distribution networks requiring multiple delayed phases
• High-speed data acquisition systems for sampling alignment
• Timing synchronization circuits in telecommunications equipment

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the presence of the 'uSOP' package designation and ensure the ordering suffix matches the required tape and reel configuration. Cross-reference the part number with current discontinuation notices from Analog Devices or Maxim Integrated to confirm availability status before finalizing procurement plans.

Selection Notes

Select this specific model when a fixed 6ns delay is required across three channels. Ensure the system operates strictly within the 4.75V to 5.25V supply range to maintain specified timing tolerances. Verify that the 8-pin uSOP footprint aligns with the PCB layout constraints, as alternative packages like SOIC are not available for this specific suffix combination.

Part Context

This component belongs to the DS1135 series, which serves as a low-power, high-speed successor to the DS1013 and DS1035 families. The series is designed to replace older discrete timing solutions by consolidating multiple delay lines into a single integrated circuit. The 'U' designation specifically identifies the smaller uSOP package variant compared to the standard SOIC versions.
