DS1100LU-25

Delay Lines IC Overview

The DS1100LU-25 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 25ns (Taps 1–5: 5ns, 10ns, 15ns, 20ns, 25ns). The device utilizes low-power CMOS technology in an 8-pin µMAX package. It ensures precise reproduction of both leading and trailing edges with input-to-tap delay tolerances ranging from ±2ns to ±4ns depending on temperature. Each tap can drive up to 10 LS loads.

Delay Lines IC Feature Summary

• All-silicon timing circuit with five equally spaced taps
• Precise leading- and trailing-edge accuracy
• Low-power CMOS construction compatible with TTL and CMOS logic levels

Delay Lines IC Applications

• Precision timing circuits requiring fixed delays
• Pulse shaping and signal synchronization
• Clock distribution networks

Delay Lines IC Procurement Notes

Verify the specific suffix against official documentation to confirm lead-free status and packaging format. Confirm that the ordering code matches the required delay value and package type. Ensure compatibility with the intended operating voltage range of 3.0V to 3.6V before procurement.

Delay Lines IC Selection Notes

Select this component when a fixed 25ns total delay with intermediate taps is required. Consider the -25 suffix for the specific delay profile. Evaluate the µMAX package for space-constrained PCB layouts. 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 family of economy timing elements. The 'LU' designation indicates the µMAX surface-mount package variant. The '-25' suffix specifies the 25ns total delay configuration. It serves as a silicon-based alternative to hybrid delay lines.

Delay Lines IC Replacement Considerations

Check for DS1100LU-xxx variants with different delay values if the 25ns specification does not match the design requirement. Verify pinout compatibility with existing designs using SO or other µMAX packages within the same family.
