DS1000M-20

Overview

The DS1000M-20 is a tapped delay line integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides five equally spaced taps with a total available delay of 20 nanoseconds. The device operates on a single 5V supply, with voltage specifications ranging from 4.75V to 5.25V. It features TTL/CMOS-compatible logic levels and low-power CMOS construction. The component is housed in an 8-pin PDIP package designed for through-hole mounting. It supports an industrial operating temperature range from -40°C to +85°C. The unit delivers precise time delays with leading and trailing edge accuracy.

Feature Summary

• Provides five equally spaced output taps for precise signal timing adjustments
• Features all-silicon construction ensuring superior reliability over hybrid technology
• Maintains stable and precise delay characteristics with specified tolerance limits
• Supports standard vapor phase, IR, and wave soldering processes

Applications

• Signal processing circuits requiring precise time delay elements
• Timing adjustment in communication systems
• Replacement for hybrid delay lines in existing PCB designs

Procurement Notes

Verify component authenticity due to discontinued status. Check datasheet revisions for manufacturing changes. Confirm RoHS compliance details before integration. Validate package dimensions against current design constraints. Ensure supply chain stability for legacy parts.

Selection Notes

Compare total delay requirements against the 20ns specification. Verify compatibility with 5V logic families. Assess thermal management needs within the -40°C to +85°C range. Consider pinout compatibility if replacing hybrid equivalents. Evaluate space constraints for the 8-pin DIP footprint.

Part Context

This component belongs to the DS1000 series of silicon delay lines. The series offers various delay values and packaging options including 14-pin DIP and surface mount variants. The M suffix typically denotes military or extended temperature grade specifications within the Maxim product line.

Replacement Considerations

DS1000M-20+ serves as the direct lead-free replacement variant. Other series members like DS1000M-100 offer different delay values but share similar packaging.
