DS1100LU-300

Delay Lines IC Overview

The DS1100LU-300 is a 3.3V, five-tap silicon delay line manufactured by Analog Devices/Maxim Integrated in an 8-pin µMAX package. It provides equally spaced delays with a nominal total delay of 300ns across taps 1 through 5 (60ns, 120ns, 180ns, 240ns, and 300ns respectively). The device operates within a supply voltage range of 3.0V to 3.6V and supports an operating temperature range from -40°C to +85°C. It features low-power CMOS technology, TTL/CMOS compatibility, and high precision for both leading and trailing edges.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays
• Five equally spaced taps with equal precision for leading and trailing edges
• Low-power CMOS construction compatible with TTL and CMOS logic levels

Delay Lines IC Applications

• Timing element requiring fixed delay intervals
• Pulse shaping and synchronization circuits
• Digital signal processing applications needing precise edge reproduction

Delay Lines IC Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and compliance status. Confirm availability through authorized distributors as lead times may vary. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Delay Lines IC Selection Notes

Select the DS1100LU-300 when a 300ns total delay with five intermediate taps is required in a surface-mount configuration. Consider the 3.3V operating voltage and industrial temperature range (-40°C to +85°C) during design. Verify that the load requirements do not exceed the drive capability of up to ten 74LS loads per tap.

Delay Lines IC Part Context

The DS1100LU-300 belongs to the DS1100L series, which serves as the 3.3V version of the original DS1100 family. This series utilizes 100% silicon delay lines housed in industry-standard µMAX or SO packages to reduce PCB area while maintaining reliability superior to hybrid technologies.

Delay Lines IC Replacement Considerations

Compatible substitutes include other variants within the DS1100L series, such as the DS1100LU-xxx+T, depending on the required delay value. Cross-reference pinouts and electrical characteristics to ensure functional equivalence.
