DS1135U-30+T&R

Overview

The DS1135U-30+T&R is a high-speed silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It integrates three independent buffered delays within an 8-pin uSOP package. The device operates on a +5V supply voltage ranging from 4.75V to 5.25V, with an active current of 35mA at maximum voltage. Each output provides a fixed delay of 30ns, characterized by initial tolerances of ±1.5ns and temperature/voltage drifts up to ±2ns over the industrial range of -40°C to +85°C. Output rise and fall times are typically 2.5ns, supporting driving capabilities for up to 10 LS loads.

Feature Summary

• Integrates three independent logic buffered delays in a single package
• Maintains stable and precise timing performance across temperature and voltage variations
• Preserves input symmetry through precise leading and trailing edge accuracy
• Provides inherent reliability as an all-silicon timing circuit solution

Applications

• Precision timing circuits requiring multiple synchronized delays
• Replacement for legacy DS1013 and DS1035 delay lines
• High-speed digital signal processing synchronization

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the presence of the 'uSOP' package designation and '+T&R' suffix indicating tape and reel packaging. Ensure compliance with RoHS standards as indicated by the '+' symbol in the part number. Cross-reference serial codes with distributor documentation to prevent counterfeit components.

Selection Notes

Select this model when a fixed 30ns delay is required for three independent channels. Compare against the DS1135Z series if a standard 150-mil SOIC package is preferred over the compact 118-mil uSOP form factor. Consider the DS1135L series if the application requires 3V operation instead of the standard 5V supply. Verify that the 30ns delay aligns with system timing requirements before finalizing the design.

Part Context

This component belongs to the DS1135 series, which represents a low-power, high-speed evolution of the DS1013 and DS1035 families. The series is designed to provide reliable all-silicon timing solutions. The specific U variant denotes the 8-pin uSOP package, distinguishing it from the Z (SOIC) and M (DIP) package options available within the broader product family.
