DS1100LU-250+

Delay Lines IC Overview

The DS1100LU-250+ is a 3.3V, five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated in an 8-pin µMAX surface-mount package. It provides equally spaced delays ranging from 4ns to 500ns; the -250 suffix specifies a nominal total delay of 250ns across its taps. The device operates on a supply voltage between 3.0V and 3.6V with an active current of 10mA at 1MHz. It features low-power CMOS technology, TTL/CMOS compatibility, and precise leading/trailing-edge reproduction. The component supports vapor-phase and IR soldering and functions within an operating temperature range of -40°C to +85°C.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays
• Five equally spaced taps for flexible timing configurations
• Low-power CMOS design compatible with TTL and CMOS logic levels

Delay Lines IC Applications

• Timing element generation in digital circuits
• Pulse width extension or compression applications
• Clock signal distribution networks requiring fixed delays

Delay Lines IC Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm lead-free status and tape-and-reel packaging requirements. Ensure that the selected variant matches the required delay tolerance specifications for your application environment. Cross-reference the datasheet revision history to confirm the accuracy of electrical characteristics before finalizing procurement orders.

Delay Lines IC Selection Notes

Select this component when a fixed, multi-tap delay profile is required without programmability. The -250 designation indicates a 250ns total delay, resulting in approximately 50ns increments per tap. Consider the µMAX package size if PCB area is constrained. Verify that the input pulse width meets the minimum requirement relative to the tap delay values to ensure accurate timing performance.

Delay Lines IC Part Context

This part belongs to the DS1100L series, which serves as the 3.3V version of the standard DS1100 family. The series offers various delay options from 4ns to 500ns, allowing designers to choose specific timing intervals. The LU suffix denotes the µMAX package, while the plus sign indicates RoHS compliance. This series replaces older hybrid technologies with cost-effective silicon solutions.

Delay Lines IC Replacement Considerations

The DS1100U-250+ is a documented equivalent offering identical functional specifications and delay characteristics. Both parts provide five taps with a 250ns total delay. Verify that the alternative package type aligns with your board layout constraints before substitution.
