DS1005S-250+

Overview

The DS1005S-250+ is a five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced delays ranging from 50 ns to 250 ns with an accuracy of ±2 ns or ±3%, whichever is greater. The device operates on a single 5V supply (4.75V to 5.25V) and features TTL/CMOS compatibility. It is housed in a 16-pin SOIC package, suitable for surface-mount applications.

Feature Summary

• Provides five equally spaced time-delay taps
• Ensures stable and precise timing over temperature and voltage variations
• Maintains accuracy on both leading and trailing signal edges
• Compatible with standard TTL and CMOS logic families

Applications

• Timing circuits requiring fixed propagation delays
• Pulse shaping and synchronization systems
• Digital logic interface timing adjustments

Procurement Notes

Verify the specific suffix 'S' indicates the 16-pin SOIC package variant. Confirm the '+T&R' designation if tape-and-reel packaging is required for automated assembly processes. Ensure the component meets RoHS compliance standards before integration into final assemblies.

Selection Notes

Select this model when a total delay of 250 ns across five taps is required. Verify that the 16-pin SOIC footprint matches the PCB layout constraints. Ensure the application environment remains within the specified 0°C to 70°C operating temperature range for guaranteed performance specifications.

Part Context

This component belongs to the DS1005 series of all-silicon delay lines. It serves as a direct replacement for older hybrid technology delay lines while offering superior reliability. The device maintains pin compatibility with standard DIP packages despite being offered in a surface-mount configuration.

FAQ

What is the delay accuracy specification?

The delay tolerance is ±2 ns or ±3%, whichever is greater.

How does temperature affect the delay?

All tap delays vary unidirectionally with temperature; if one tap slows down, all others slow down proportionally.

What is the maximum input pulse width requirement?

The minimum input pulse width must be at least 40% of the Tap 5 delay time.
