DS1000K-250

Overview

The DS1000K-250 is a tapped delay line integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides a total programmable delay of 250 nanoseconds, distributed across five taps with an increment of 50 ns per tap. The device operates on a single supply voltage ranging from 4.75 V to 5.25 V and supports through-hole installation in an 8-pin PDIP package. It functions as a single-emitter programmable delay line suitable for timing applications within the specified temperature range.

Feature Summary

• Provides precise signal timing adjustments via a tapped delay architecture
• Features a single emitter configuration for straightforward integration
• Offers programmable delay steps for flexible timing control

Applications

• Signal processing circuits requiring specific time delays
• Timing adjustment in digital communication systems
• Pulse shaping and synchronization tasks

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as this part may be discontinued. Ensure the supplier provides valid traceability documentation matching the original Analog Devices/Maxim Integrated specifications before finalizing any acquisition.

Selection Notes

Select this component when a fixed 250 ns total delay with 50 ns resolution is required. Ensure the system power supply strictly maintains the 4.75 V to 5.25 V range. Verify that the 8-pin PDIP package fits the target PCB layout constraints and that the operating temperature range meets environmental requirements.

Part Context

This device belongs to the DS1000 series of tapped delay lines designed for precision timing applications. It shares functional similarities with other parts in the family but is distinguished by its specific 250 ns total delay capability and 5-tap structure. The K suffix typically denotes a specific performance grade or package variant within the broader product line.

Replacement Considerations
