DS1000Z-20

Overview

The DS1000Z-20 is a tapped delay line integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed propagation delay of 20 nanoseconds per tap, serving as an economical timing element for digital circuits. The device operates within a supply voltage range of 4.75V to 5.25V and supports both CMOS and TTL logic families. It is housed in an 8-pin SOIC package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides precise 20ns propagation delay characteristics suitable for timing applications
• Compatible with standard CMOS and TTL logic families for broad integration
• Features a compact surface-mount SOIC-8 package design

Applications

• Digital signal processing timing adjustments
• Pulse width modulation synchronization
• Clock skew compensation in high-speed data paths

Procurement Notes

Verify the specific suffix designation when sourcing components, as it indicates the packaging format such as tube or reel. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the supplier source is authorized to guarantee component authenticity and traceability throughout the supply chain.

Selection Notes

Select this component when a fixed 20ns delay is required without programmability. Verify that the operating environment remains within the specified -40°C to +85°C range. Ensure the system power supply strictly adheres to the 4.75V to 5.25V limits to maintain signal integrity and prevent device malfunction during operation.

Part Context

This part belongs to the DS1000Z series of tapped delay lines designed for cost-effective timing solutions. It shares functional similarities with other members like the DS1100Z but offers distinct delay characteristics. The series is widely used in legacy and modern digital systems requiring reliable, fixed-delay performance.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative delay lines based on matching 20ns delay specifications and compatible logic family support before considering cross-references.
