DS1000S-45

Overview

The DS1000S-45 is a tapped delay line timing element manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a fixed propagation delay of 45 nanoseconds across five taps, functioning as an economy timing element for digital circuits. The device operates within a standard single-supply voltage range of 4.75 V to 5.25 V and supports surface-mount installation in an SOIC-8 package. It is rated for industrial temperature operation from -40°C to +85°C. Electrical characteristics include a low-level output current capability of 12 mA and a high-level output current of -1 mA, with a typical operating supply current of 30 mA.

Feature Summary

• Provides fixed multi-tap delay functionality without programmability requirements
• Designed for economical integration into timing-critical digital applications
• Supports standard surface-mount technology for automated assembly processes

Applications

• Digital signal processing synchronization
• Timing alignment in data acquisition systems
• Pulse width adjustment in control circuits

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm RoHS compliance status and specific lot traceability prior to procurement. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage during soldering. Validate that the ordered suffix matches the required tape-and-reel or tube packaging configuration for your assembly line equipment.

Selection Notes

Select this component when a fixed 45 ns delay is required across multiple outputs without the need for variable adjustment. Compare against the DS1100Z series for similar performance in standard voltage environments. Consider the DS1100LZ series if lower voltage operation near 3 V is necessary instead of the standard 5 V rail. Verify pin compatibility with existing PCB footprints before finalizing the design.

Part Context

This part belongs to the DS1000/DS1100 family of tapped delay lines designed for cost-sensitive timing applications. These components serve as alternatives to discrete RC networks or complex programmable logic devices for simple delay tasks. The series is characterized by its simplicity, requiring minimal external components while providing precise, factory-trimmed delay values for reliable system timing.

Replacement Considerations

The DS1000S-45 is generally considered obsolete. Potential functional substitutes within the same family include the DS1100Z-45+ for standard voltage applications or the DS1100LZ-45+ for lower voltage requirements. Verify pinout compatibility and electrical specifications before substituting.
