DS1135U-20

Delay Lines IC Overview

The DS1135U-20 is a high-speed, all-silicon delay line featuring three independent buffered delays within an 8-pin uSOP package. It operates on a single +5V supply (4.75V to 5.25V) and provides a nominal delay of 20ns per output tap. The device maintains stable timing over temperature ranges from -40°C to +85°C with specific tolerance limits for initial accuracy and environmental variations. Each output can drive up to 10 LS loads, ensuring compatibility with standard logic families while preserving input symmetry through precise leading and trailing edge control.

Delay Lines IC Feature Summary

• Three independent buffered delay channels integrated into a single compact package
• High-speed silicon architecture providing stable and precise timing performance
• Preserves input signal symmetry via accurate leading and trailing edge delay characteristics

Delay Lines IC Applications

• Precision timing circuits requiring multiple synchronized delayed signals
• Waveform shaping and pulse generation systems
• Digital logic synchronization and clock distribution networks

Delay Lines IC Procurement Notes

Verify the exact ordering suffix against current manufacturer documentation, as package types and RoHS compliance status may vary between manufacturing runs. Confirm availability status directly with authorized distributors or the manufacturer, as lead times and stock levels fluctuate based on production schedules and regional supply constraints.

Delay Lines IC Selection Notes

Select this component when three identical delay paths are required in a space-constrained design. Ensure the system operates within the specified 4.75V to 5.25V voltage range and that the 20ns delay value aligns with the target timing requirements. Verify that the load capacitance and drive capability meet the downstream logic interface specifications.

Delay Lines IC Part Context

This device belongs to the DS1135 series of high-speed silicon delay lines, serving as a faster successor to the DS1013 and DS1035 models. The 'U' designation indicates the 8-pin micro-small outline package variant, distinct from the standard SOIC package found in other series members. It is designed for applications demanding reliable, all-silicon timing solutions without the variability of discrete components.

Delay Lines IC Replacement Considerations

The datasheet explicitly recommends the DS1135Z-20+ as a direct replacement option for users requiring the same 20ns delay specification but preferring the standard 8-pin SOIC (150-mil) package format instead of the uSOP configuration.
