DS1135U-15

Delay Lines IC Overview

The DS1135U-15 is a high-speed silicon delay line featuring three independent buffered delays within a single package. It operates on a +5V supply with a voltage range of 4.75V to 5.25V and functions across an industrial temperature range of -40°C to +85°C. The device provides a nominal delay of 15ns per output, with an initial tolerance of ±1.5ns at room temperature and ±2ns over the full operating range. It utilizes an 8-pin uSOP (uMAX) surface-mount package.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays over temperature and voltage variations
• Three independent buffered delay outputs capable of driving up to 10 LS loads each
• Leading and trailing edge precision preserves input signal symmetry

Delay Lines IC Applications

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

Delay Lines IC Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence or limited availability. Confirm that the 8-pin uSOP footprint matches the target PCB design. Ensure power supply decoupling meets the datasheet recommendations to maintain timing accuracy under dynamic load conditions.

Delay Lines IC Selection Notes

Select the DS1135U-15 when a fixed 15ns delay is required for three independent signals in a compact surface-mount package. Compare against the DS1135Z-15 if a standard SOIC footprint is preferred instead of the narrower uSOP variant. Verify that the 5V logic levels are compatible with the system's input and output voltage thresholds.

Delay Lines IC Part Context

The DS1135 series represents a low-power, high-speed evolution of the DS1013 and DS1035 families. It consolidates three independent delay lines into one package, offering faster performance than its predecessors. The U suffix denotes the 8-pin uSOP package, while the Z suffix indicates the standard 150-mil SOIC package.

Delay Lines IC Replacement Considerations

DS1135Z-15+ offers identical electrical characteristics in a standard 150-mil SOIC package.
