DS1135U-8/T&R

Overview

The DS1135U-8/T&R is a high-speed, all-silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It integrates three independent buffered delays within a single package, designed for stable and precise timing over temperature and voltage variations. The device operates on a +5V supply (4.75V to 5.25V) and features leading and trailing edge precision that preserves input symmetry. Each output can drive up to 10 LS loads. The specific model provides an 8ns delay per output with an initial tolerance of ±1.0ns at nominal conditions (+25°C, VCC=+5.0V). It supports commercial and industrial temperature ranges (-40°C to +85°C) and is available in tape and reel packaging.

Feature Summary

• Integrates three independent logic buffered delays in a single package
• Provides stable and precise timing performance across temperature and voltage variations
• Preserves input symmetry through leading and trailing edge precision
• Capable of driving up to 10 LS loads per output

Applications

• Precision timing circuits requiring multiple synchronized delays
• High-speed signal processing applications
• Replacement for legacy DS1013 and DS1035 devices

Procurement Notes

Verify the part number suffix against official documentation to confirm RoHS status and packaging type. Ensure the ordering code matches the required delay value and package style. Confirm availability through authorized distributors as lead times may vary. Check datasheet specifications for absolute maximum ratings to prevent damage during handling or operation.

Selection Notes

Select this component when three independent delay channels are required in a compact form factor. Choose based on the specific nanosecond delay value needed from the standard options. Consider the 8-pin SOIC package constraints and surface mount installation requirements. Verify compatibility with existing system voltage levels and load driving capabilities.

Part Context

The DS1135 series represents a low-power, high-speed evolution of the popular DS1013 and DS1035 delay lines. It serves as the fastest 3-in-1 silicon delay line solution in its class. The device is recommended as a direct replacement for older discrete or less integrated timing components in established designs.

FAQ

What is the typical output rise or fall time for the DS1135U-8?

The typical output rise or fall time is 2.5 ns, with a maximum specified value of 2.0 ns under test conditions.

How does the DS1135 preserve input symmetry?

It utilizes precise leading and trailing edge accuracy to ensure that the timing characteristics of the input pulse are maintained at the outputs.

What is the power-up time for the device?

The power-up time is typically 100 ms, which is the duration from applying power until stable delays are produced at the outputs.
