DS1135LU-15+TR

Overview

The DS1135LU-15+TR is a high-speed silicon delay line manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates three independent delay lines within a single uSOP-8 surface-mount package. The device operates on a low voltage supply ranging from 2.7 V to 3.6 V, making it suitable for portable applications. Each channel provides a fixed propagation delay of 15 ns with true output polarity. The component supports an industrial operating temperature range from -40°C to +85°C and utilizes a tape-and-reel packaging format for automated assembly processes.

Feature Summary

• Integrates three independent high-speed silicon delay lines in a compact footprint
• Operates on a low-voltage power supply suitable for battery-powered systems
• Provides fixed 15 ns propagation delay per channel with true output logic
• Designed for surface-mount technology using a small outline package

Applications

• Precision timing alignment in digital signal processing circuits
• Clock skew compensation in high-speed data interfaces
• Pulse width adjustment in measurement instrumentation

Procurement Notes

Verify the specific suffix configuration when sourcing this component, as packaging variations exist within the product family. Confirm that the manufacturer has not issued a formal end-of-life notification or product change notice affecting availability. Ensure the supplier provides valid traceability documentation for the analog devices integrated circuit to guarantee authenticity and compliance with environmental standards.

Selection Notes

Select this model when a low-voltage 3V operation is required rather than the standard 5V variants. The fixed 15 ns delay specification suits applications needing precise, non-adjustable timing offsets. Consider the uSOP-8 package dimensions against board space constraints. Verify that the single-ended true output architecture aligns with the system's input requirements without necessitating additional inversion stages.

Part Context

This component belongs to the DS1135 series of silicon delay lines, which are designed for precision timing control. The LU suffix indicates the specific low-voltage variant and package type. The TR suffix denotes the tape-and-reel packaging method used for high-volume manufacturing. This series offers a compact alternative to discrete timing components for maintaining signal integrity in synchronous digital systems.

Replacement Considerations

Cross-reference with other DS1135 series members such as the DS1135U-15 for 5V operation compatibility. Check for pin-compatible alternatives if the system design allows for voltage level adjustments. Verify that any substitute maintains the same 15 ns delay tolerance and package footprint to ensure mechanical fit.
