DS1100LU-25+T

Delay Lines IC Overview

The DS1100LU-25+T is a 3.3V five-tap silicon delay line manufactured by Analog Devices/Maxim Integrated in an 8-pin µMAX surface-mount package. It provides equally spaced output taps with a nominal total delay of 25ns, resulting in individual tap delays of 5ns, 10ns, 15ns, 20ns, and 25ns. The device operates within a supply voltage range of 3.0V to 3.6V and supports an industrial temperature range from -40°C to +85°C. It features low-power CMOS technology with TTL and CMOS compatibility, capable of driving up to ten 74LS loads per tap.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays across five equally spaced taps
• Ensures equal precision for both leading-edge and trailing-edge signal reproduction
• Low-power CMOS construction compatible with standard TTL and CMOS logic families

Delay Lines IC Applications

• Precision timing element generation for digital circuits
• Signal synchronization and pulse stretching applications
• Clock distribution networks requiring specific delay intervals

Delay Lines IC Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the ordering suffix matches the required lead-free RoHS compliance status and tape-and-reel packaging format. Ensure the specific delay variant aligns with the design requirements before finalizing procurement orders.

Delay Lines IC Selection Notes

Select this component when a fixed, low-cost silicon delay solution is preferred over hybrid technologies. The 25ns total delay variant is suitable for applications requiring short, precise time intervals. Consider the µMAX package dimensions for PCB area constraints and verify that the load requirements do not exceed the specified drive capability per tap.

Delay Lines IC Part Context

This part belongs to the DS1100L series, which serves as the 3.3V version of the original DS1100 family. The series offers various delay options ranging from 4ns to 500ns, allowing designers to choose specific timing characteristics without custom fabrication. The LU suffix indicates the use of the industry-standard µMAX surface-mount package.

Delay Lines IC Replacement Considerations

The DS1100LU-25+ is a direct pin-compatible replacement for the non-RoHS compliant DS1100LU-25. Other variants within the DS1100L family share the same package but offer different delay values.
