DS1100LZ-250+T

Delay Lines IC Overview

The DS1100LZ-250+T is a 3.3V tapped delay line from the DS1100L series, characterized for operation between 3.0V and 3.6V. It features five equally spaced taps providing a nominal total delay of 250ns, with individual tap delays of 50ns, 100ns, 150ns, 200ns, and 250ns. The device utilizes an all-silicon timing circuit in an 8-pin SO package. It operates within a temperature range of -40°C to +85°C and includes lead(Pb)-free/RoHS-compliant packaging.

Delay Lines IC Feature Summary

• Five equally spaced taps provide stable and precise silicon-based timing delays.
• Designed to reproduce both leading and trailing edges with equal precision.
• Low-power CMOS technology compatible with TTL and CMOS logic families.

Delay Lines IC Applications

Delay Lines IC Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm RoHS compliance status via official datasheets. Ensure ordering suffixes match required packaging formats such as tape and reel. Validate supply chain documentation against current manufacturer specifications.

Delay Lines IC Selection Notes

Select this model when a fixed 250ns total delay with five intermediate taps is required. Verify that the 3.3V operating voltage aligns with system power rails. Consider the SO-8 package dimensions for PCB layout constraints. Ensure input pulse width requirements meet the minimum specifications outlined in the AC electrical characteristics.

Delay Lines IC Part Context

This component belongs to the DS1100L family of 3.3V economy timing elements. It serves as a surface-mount alternative to hybrid delay technologies, offering superior reliability and lower cost. The series provides various delay values ranging from 4ns to 500ns across different part numbers.

Delay Lines IC Replacement Considerations

DS1100LZ-250+ is the tube-packaged equivalent. DS1100LU-250+ offers the same electrical performance in a µMAX package. Cross-reference specific delay tolerances and package footprints before substitution.

Delay Lines IC FAQ

What is the delay tolerance for the DS1100LZ-250+T?

For delays greater than 40ns, the input-to-tap delay tolerance is specified as -13% to +13% over the industrial temperature range (-40°C to +85°C).

How many loads can each tap drive?

Each tap is capable of driving up to 10 standard 74LS loads.

What is the maximum input pulse width requirement?

The input pulse width must be at least 20% of the Tap 5 delay time. For the -250 version, this requires a minimum pulse width of 50ns.
