DS1100U-25+

Delay Lines IC Overview

The DS1100U-25+ is a five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced timing taps with a nominal total delay of 25 nanoseconds, resulting in individual tap delays of 5ns, 10ns, 15ns, 20ns, and 25ns. The device operates on a single +5V supply within a range of 4.75V to 5.25V. It utilizes low-power CMOS technology and features TTL/CMOS-compatible logic levels. The component is housed in an 8-pin µMAX surface-mount package and supports operation across the industrial temperature range of -40°C to +85°C.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays over commercial and industrial temperature ranges
• Five equally spaced taps designed to reproduce both leading and trailing edges with equal precision
• Low-power CMOS construction compatible with standard TTL and CMOS logic families

Delay Lines IC Applications

• Timing element replacement for legacy DS1000 hybrid circuits
• PCB area-saving applications utilizing surface-mount packaging
• Fast-turn prototype development requiring custom or standard delay values

Delay Lines IC Procurement Notes

Verify the specific ordering suffix to confirm compliance status and packaging format. The plus sign indicates lead-free and RoHS-compliant manufacturing. Confirm that the µMAX package footprint matches the target PCB design. Ensure the selected delay value aligns with the required timing specifications for the application.

Delay Lines IC Selection Notes

Select this part when a fixed 25ns total delay is required with intermediate sampling points. Compare against other DS1100 variants if different delay totals are needed. Consider the SOIC package option if µMAX availability is limited. Verify that the 5V operating voltage matches the system power rails.
