DS1005-125+

Overview

The DS1005-125+ is a five-tap silicon delay line providing equally spaced delays ranging from 12 ns to 250 ns. This specific model delivers tap delays of 25 ns, 50 ns, 75 ns, 100 ns, and 125 ns with an accuracy of ±2 ns or ±3%, whichever is greater. It operates on a single +5V supply (4.75V to 5.25V) with a typical active current of 70 mA. The device supports TTL/CMOS logic levels and features both leading and trailing edge accuracy. Available in standard 14-pin DIP, 8-pin DIP, or 16-pin SOIC packages, it is designed for stable performance across the 0°C to +70°C operating temperature range.

Feature Summary

• Provides five equally spaced output taps with precise delay intervals
• Maintains high accuracy on both rising and falling signal edges
• Compatible with standard TTL and CMOS logic families
• Offers low-power CMOS construction with industry-standard packaging

Applications

• Timing alignment in digital communication systems
• Pulse width modulation circuitry
• Clock distribution networks requiring fixed delays
• Signal processing applications needing precise timing offsets

Procurement Notes

Verify package availability as the component may be offered in multiple form factors including through-hole and surface-mount options. Confirm that the required delay specifications match the exact tap values needed for the design. Ensure the operating environment remains within the specified temperature limits to maintain guaranteed accuracy. Check for updated documentation regarding end-of-life status or alternative sourcing channels if direct procurement is restricted.

Selection Notes

Select this component when fixed, equally spaced delays are required without programmable adjustment. Consider the 14-pin DIP version for prototyping or legacy board compatibility. Evaluate the load driving capability, as each tap can drive up to ten 74LS loads. Verify that the input pulse width meets the minimum requirement to ensure accurate delay performance across all taps.

Part Context

This part belongs to the DS1005 series of silicon delay lines manufactured by Analog Devices Inc./Maxim Integrated. The series provides various delay increments from 12 ns to 250 ns. The DS1005-125+ specifically targets applications requiring a maximum delay of 125 ns. It replaces older hybrid technology delay lines with a fully silicon-based solution for improved reliability and lower cost.

Replacement Considerations

Direct replacements include other models within the DS1005 series such as DS1005-100+ or DS1005-150+ if different delay values are acceptable. Cross-reference tables provided by the manufacturer should be consulted for equivalent-density NV SRAM modules or similar timing elements if architectural changes are permitted.
