DS1135Z-20

Overview

The DS1135Z-20+ is a high-speed, all-silicon delay line from the DS1135 series manufactured by Analog Devices Inc./Maxim Integrated. It integrates three independent buffered delays within a single package, operating on a +5V supply voltage ranging from 4.75V to 5.25V. The device provides a nominal delay of 20ns per output with an initial tolerance of ±1.0ns at +25°C and VCC = +5.0V. It maintains stable timing over temperature and voltage variations, featuring precise leading and trailing edge accuracy that preserves input symmetry. The component is housed in an 8-pin SOIC (150-mil) package and supports commercial and industrial temperature ranges.

Feature Summary

• Integrates three independent logic buffered delays in a single package
• Provides precise leading and trailing edge accuracy to preserve input symmetry
• Features inherent reliability as an all-silicon timing circuit solution
• Capable of driving up to 10 LS loads per output

Applications

• High-speed signal timing adjustments
• Pulse width modulation circuits
• Clock distribution networks requiring precise delay matching

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm RoHS compliance status, as indicated by symbols such as '+', '#', or '-' in the package code. Confirm the package type corresponds to the standard 8-pin SOIC (150-mil) outline. Ensure compatibility with vapor phasing, IR reflow, and wave soldering processes during assembly planning.

Selection Notes

Select the DS1135Z-20+ when a fixed 20ns delay is required for each of the three channels. Consider the DS1135L series if the application operates at 3V instead of 5V. Evaluate the initial tolerance specifications (+/-1.0ns) against system requirements, noting that tolerance increases to +/-2ns over the full -40°C to +85°C temperature range.

Part Context

The DS1135 series serves as a low-power, high-speed successor to the DS1013 and DS1035 families. It represents the fastest 3-in-1 delay line option available in the lineup. The Z suffix specifically denotes the standard 8-pin SOIC package variant, distinguishing it from other form factors previously offered in the broader product family.

Replacement Considerations

Officially recommended replacements include the DS1013 and DS1035 models.
