DS1135U-8+T&R

Overview

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

Feature Summary

• Three independent buffered delay channels integrated into a single package
• Precise leading and trailing edge accuracy preserves input symmetry
• All-silicon construction ensures inherent reliability and stability
• Compatible with vapor phasing, IR, and wave soldering processes

Applications

• Precision timing circuits requiring multiple synchronized delays
• Replacement for legacy DS1013 and DS1035 delay lines
• High-speed logic buffering with specific propagation requirements

Procurement Notes

Verify the component status as discontinued or obsolete through official Analog Devices channels before design finalization. Confirm that the tape and reel packaging meets automated assembly requirements. Ensure the 8-pin uSOP footprint matches the target PCB layout specifications. Check for RoHS compliance documentation if required by local regulations.

Selection Notes

Select this part when three identical delay paths are needed within a compact surface-mount form factor. The 8ns delay value suits applications requiring moderate signal shifting without programmability. Consider the 8-pin SOIC variant if wider pitch compatibility is necessary for existing manufacturing equipment.

Part Context

This component belongs to the DS1135 series of high-speed silicon delay lines manufactured by Maxim Integrated, now part of Analog Devices. The series offers fixed delay values optimized for precision timing tasks. The 'U' suffix denotes the 8-pin micro-SOP package, while the '+T&R' indicates RoHS-compliant tape and reel packaging.

Replacement Considerations

Officially recommended replacements include the DS1013 and DS1035 models. Verify pinout compatibility and electrical characteristics against these legacy parts to ensure seamless integration into existing designs.
