DS1135U-8

Overview

The DS1135U-8+ 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 with a voltage range of 4.75V to 5.25V and supports an operating temperature range from -40°C to +85°C. The nominal delay per output is 8ns, with an initial tolerance of ±1.0ns at 25°C and a maximum tolerance of ±1.5ns across the industrial temperature range. Each output can drive up to 10 LS loads, and the device maintains input symmetry through precise leading and trailing edge accuracy.

Feature Summary

• Integrates three independent logic buffered delays within a single low-power package
• Maintains stable and precise timing performance over varying temperature and voltage conditions
• Preserves input signal symmetry via accurate leading and trailing edge control

Applications

• High-speed timing circuits requiring multiple synchronized delays
• Replacement for legacy DS1013 and DS1035 delay lines
• Applications demanding precise pulse width and period control

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status as indicated by the suffix. Ensure the specific package type matches design requirements. Review absolute maximum ratings to prevent damage during handling or operation. Validate electrical characteristics against current production batches.

Selection Notes

Select this component when three identical delay paths are required in a compact surface-mount footprint. Compare delay tolerances against application timing budgets. Verify that the 8-pin uSOP package fits the available board space. Consider the 5V supply requirement and ensure compatibility with existing power rails. Evaluate thermal management needs within the specified operating temperature range.

Part Context

This device belongs to the DS1135 series of all-silicon timing circuits. It serves as a faster alternative to previous generations like the DS1013 and DS1035. The series offers various delay values to suit different timing requirements while maintaining consistent package dimensions and pinouts for easy integration into existing designs.
