DS1010S-250

Overview

The DS1010S-250 is a 10-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-pin SOIC package. It provides a total delay of 250 ns with a tap increment of 25 ns. The device operates on a single 4.75 V to 5.25 V supply and functions within a commercial temperature range of 0°C to +70°C. It features low-power CMOS technology with TTL/CMOS-compatible inputs and outputs. Each tap can drive up to 10 LS-type loads, ensuring precise leading and trailing edge accuracy.

Feature Summary

• Provides ten equally spaced output taps for precise time-delay applications
• Features all-silicon construction for stable and economical timing solutions
• Ensures equal precision on both leading and trailing signal edges
• Supports standard surface mount packaging for reduced printed circuit board area

Applications

• Timing circuits requiring fixed propagation delays
• Pulse stretching and shaping networks
• Clock distribution systems needing specific phase offsets
• Digital logic synchronization interfaces

Procurement Notes

Verify the exact suffix designation when sourcing replacements, as it defines the specific delay value. Confirm that the required package type matches the target design constraints. Check current availability status, as older components may have limited stock or be subject to obsolescence notices from the manufacturer.

Selection Notes

Select this component when a fixed 250 ns total delay with 25 ns steps is required. Ensure the system voltage remains within the 4.75 V to 5.25 V range for optimal performance. Verify that the load requirements do not exceed the specified drive capability per tap. Consider the operating temperature range to ensure compatibility with the intended environment.

Part Context

This part belongs to the DS1010 series of 10-tap silicon delay lines. The series offers various total delay values ranging from 50 ns to 500 ns. The 'S' suffix indicates the 16-pin SOIC surface-mount package variant, while other suffixes may denote different packages like DIP. The series serves as a modern replacement for older hybrid delay line technologies.

Replacement Considerations

Direct substitutes include other parts within the DS1010 family with matching delay characteristics. Verify pinout compatibility if replacing with similar delay lines from other manufacturers. Ensure the alternative component meets the same voltage and temperature specifications.
