DS1135U-20+

Delay Lines IC Overview

The DS1135U-20+ is a high-speed silicon delay line from the DS1135 series, featuring three independent buffered delays in an 8-pin SOIC package. It operates on a +5V supply with a nominal voltage range of 4.75V to 5.25V. The device provides a fixed propagation delay of 20ns per output tap. Initial tolerance is ±1.0ns at +25°C and VCC = +5.0V, expanding to ±2.0ns over the industrial temperature range (-40°C to +85°C) and voltage variations. It supports vapor phasing, IR, and wave soldering.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays over temperature and voltage
• Three independent buffered delays preserving input symmetry through leading and trailing edge precision
• Capable of driving up to 10 LS loads per output

Delay Lines IC Applications

• Replacement for DS1013 and DS1035 delay lines
• Precision timing circuits requiring multiple independent delays
• High-speed logic buffering applications

Delay Lines IC Procurement Notes

Verify the specific package suffix 'U' against official documentation, as the provided datasheet primarily details the 'Z' (SOIC) variant. Confirm RoHS compliance status indicated by the '+' suffix. Check current availability and lead times directly with Analog Devices or authorized distributors, as this component may be subject to supply constraints or end-of-life notices.

Delay Lines IC Selection Notes

Select the DS1135U-20+ when a fixed 20ns delay is required across three independent channels. Ensure the system operates within the specified +5V supply range. Consider the 8-pin SOIC footprint dimensions during PCB layout. Verify that the load requirements do not exceed the drive capability of 10 LS loads per output.

Delay Lines IC Part Context

The DS1135 series represents a low-power, high-speed version of earlier Dallas Semiconductor delay lines. It consolidates three independent delay functions into a single package, offering a compact solution for timing applications. The device is designed for reliability using all-silicon technology, eliminating the need for discrete components or external timing elements.
