DS1000M-45

Overview

The DS1000M-45 is a tapped delay line timing element manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.75 V to 5.25 V and features a propagation delay of 45 ns. The component is housed in an 8-pin PDIP package and supports surface mount or through-hole installation styles depending on the specific variant suffix. It functions as a multiple delay line suitable for precision timing applications.

Feature Summary

• Provides precise signal delay characteristics via tapped delay line architecture
• Operates with standard 5V logic supply requirements
• Designed for economy timing element applications

Applications

• Precision timing circuits requiring fixed delay intervals
• Signal synchronization systems
• Clock distribution networks

Procurement Notes

Verify the exact ordering suffix, such as M for PDIP or Z for SOIC, as these determine the physical package type. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as legacy Maxim parts may have varying environmental declarations. Ensure the selected variant matches the required thermal and mechanical constraints for the target PCB layout.

Selection Notes

Select this component when a fixed 45 ns delay is required without programmable adjustment. Compare against the DS1100Z series if a 5-tap configuration is needed instead of the standard single tap. Verify that the 5V operating voltage aligns with the system power rails and that the PDIP or SOIC package fits the available footprint.

Part Context

This part belongs to the DS1000/DS1100 family of tapped delay lines from Maxim Integrated. These components are designed to provide accurate time delays for digital signals. The DS1000 series typically offers a single delay tap, whereas the DS1100 series provides multiple taps for more complex timing sequences.

Replacement Considerations

The DS1000L-45+ serves as a low-voltage alternative operating at 3V. For multi-tap requirements, the DS1100Z-45+ is a compatible upgrade within the same delay specification but with additional output taps.
