DS1135Z-20+

Overview

The DS1135Z-20+ is a high-speed silicon delay line from the DS1135 series, manufactured by Analog Devices Inc./Maxim Integrated. It integrates three independent buffered delays in an 8-pin SOIC package. The device operates on a +5V supply with a voltage range of 4.75V to 5.25V and functions within a temperature range of -40°C to +85°C. Each output provides a nominal delay of 20ns, with initial tolerances of ±1.0ns at +25°C and ±2ns across the industrial temperature range. The component features precise leading and trailing edge accuracy, preserving input symmetry, and can drive up to 10 LS loads.

Feature Summary

• Integrates three independent logic buffered delays within a single package
• Maintains stable and precise timing performance over temperature and voltage variations
• Preserves input signal symmetry through accurate leading and trailing edge precision

Applications

• Timing circuit applications requiring multiple synchronized delayed signals
• Replacement for legacy DS1013 and DS1035 delay lines
• High-speed digital systems needing precise pulse width control

Procurement Notes

Verify RoHS compliance status using the specific ordering suffix, as indicated in the datasheet. Confirm package type availability, noting that revisions may affect offered formats. Check current distribution channels for stock levels, as availability varies by region. Ensure the selected variant matches the required delay tolerance specifications for the intended application environment.

Selection Notes

Select the DS1135Z-20+ when a fixed 20ns delay per channel is required. Compare against other series members like the DS1135Z-15+ or DS1135Z-25+ if different delay values are needed. Consider the DS1135L series for 3V operation requirements. Verify that the 8-pin SOIC package fits the board layout constraints and soldering process capabilities.

Part Context

The DS1135 series serves as a low-power, high-speed alternative to older discrete delay solutions. It consolidates three delay lines into one component, reducing board space compared to using separate devices. The Z suffix denotes the standard 150-mil SOIC package, distinguishing it from other form factors in the broader family.

Replacement Considerations

Officially recommended replacements include the DS1013 and DS1035. Designers upgrading from these legacy parts should verify pin compatibility and electrical parameter alignment before implementation.
