DS1100U-500+

Delay Lines IC Overview

The DS1100U-500+ is a five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced output taps with a nominal total delay of 500ns, resulting in individual tap delays of 100ns, 200ns, 300ns, 400ns, and 500ns. The device operates on a single +5V supply within a voltage 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 applications requiring fixed signal propagation delays
• Replacement for legacy DS1000 hybrid delay lines
• Prototyping circuits needing fast-turnaround silicon-based timing solutions

Delay Lines IC Procurement Notes

Verify the specific ordering suffix to confirm the package type and RoHS compliance status. Confirm that the required delay value matches the part number designation. Ensure the operating environment remains within the specified voltage and temperature limits. Check for any custom delay requirements not covered by standard part numbers.

Delay Lines IC Selection Notes

Select this component when a fixed 500ns total delay with five intermediate taps is required. Consider the µMAX package for space-constrained surface-mount designs. Verify that the load requirements do not exceed the drive capability of ten 74LS loads per tap. Evaluate alternative delay values if the 500ns specification does not align with system timing needs.

Delay Lines IC Part Context

This device belongs to the DS1100 series of economy timing elements. The series offers various delay values ranging from 4ns to 500ns, distinguished by the numeric suffix in the part number. The 'U' indicates the µMAX package, while the '+' denotes lead-free/RoHS-compliant manufacturing. The series serves as a modern silicon replacement for older hybrid technologies.

Delay Lines IC Replacement Considerations

The datasheet identifies the DS1100 series as an improved replacement for the DS1000. No other specific substitute part numbers are documented in the provided source material.
