DS1100U-250

Delay Lines IC Overview

The DS1100U-250 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 250ns, resulting in individual tap delays of 50ns, 100ns, 150ns, 200ns, and 250ns. The device operates within a supply voltage range of 4.75V to 5.25V and functions across an industrial temperature range of -40°C to +85°C. Packaged in an 8-pin µMAX surface-mount format, it features TTL/CMOS-compatible inputs and outputs capable of driving up to ten 74LS loads.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays for both leading and trailing edges
• Five equally spaced taps allowing for multiple fixed delay intervals from a single input
• Low-power CMOS technology compatible with standard TTL and CMOS logic families

Delay Lines IC Applications

• Timing element replacement for legacy DS1000 hybrid devices
• PCB area-saving applications requiring surface-mount delay lines
• Prototyping circuits needing fast-turnaround custom delay specifications

Delay Lines IC Procurement Notes

Verify the specific ordering suffix to confirm package type and compliance status. The 'U' designation indicates the µMAX package, while '+' denotes lead-free/RoHS compliance. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the selected variant matches the required thermal and electrical operating conditions for the target application environment.

Delay Lines IC Selection Notes

Select the DS1100U-250 when a total propagation delay of 250ns is required across five discrete output points. This model is suitable for designs utilizing 5V logic systems that demand high reliability over hybrid alternatives. Consider the µMAX package dimensions for footprint constraints. Verify that the load requirements do not exceed the specified drive capability of ten 74LS loads per tap.

Delay Lines IC Part Context

This component belongs to the DS1100 series of economy timing elements designed to replace older hybrid delay lines. The series offers various delay values ranging from 4ns to 500ns, selectable via the part number suffix. The U-series specifically utilizes the compact µMAX package, distinguishing it from the SO-package Z-series variants within the same functional family.
