DS1100U-250+T

Delay Lines IC Overview

The DS1100U-250+T is a five-tap silicon delay line from the DS1100 series, housed in an 8-pin µMAX surface-mount package. It provides equally spaced output taps with a nominal total delay of 250ns, resulting in individual tap delays of 50ns, 100ns, 150ns, 200ns, and 250ns. The device operates on a single +5V supply (4.75V to 5.25V) and features TTL/CMOS-compatible logic levels. Designed for industrial applications, it functions reliably within a 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 that reproduce both leading and trailing edges with high accuracy
• Low-power CMOS construction compatible with standard TTL and CMOS logic families

Delay Lines IC Applications

• Timing element generation for digital signal processing systems
• Clock distribution networks requiring specific phase offsets
• Pulse width modulation circuits needing precise time delays

Delay Lines IC Procurement Notes

Verify the component designation against official Analog Devices or Maxim Integrated documentation to confirm the specific delay value and package type. Ensure the ordering suffix matches the required tape-and-reel configuration and lead-free compliance status before finalizing procurement orders.

Delay Lines IC Selection Notes

Select this component when a fixed 250ns total delay with five intermediate sampling points is required. Consider the 8-pin µMAX package for space-constrained PCB layouts. Verify that the system power supply remains within the 4.75V to 5.25V range to maintain specified timing tolerances.

Delay Lines IC Part Context

This part belongs to the DS1100 family of economy timing elements manufactured by Analog Devices / Maxim Integrated. The series utilizes industry-standard packaging to replace older hybrid technologies while maintaining superior reliability. The 'U' suffix indicates the µMAX package variant, and the '+T' denotes a lead-free, RoHS-compliant version supplied in a tape-and-reel format.

Delay Lines IC Replacement Considerations

The datasheet identifies the DS1100 as an improved replacement for the DS1000 series. Designers upgrading from legacy components should verify pin compatibility and ensure the new silicon-based delay characteristics meet the original design specifications.
