DS1040Z-D70+

Overview

The DS1040Z-D70+ is a single-channel programmable delay line IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a total available delay of 70ns with five taps and a tap increment of 10 ns. The first tap delay is 30ns. Operating on a 4.75V to 5.25V supply, it functions within a commercial temperature range of 0°C to 70°C. The device is housed in an 8-SOIC package (0.154" width) and supports surface mount installation.

Feature Summary

• Programmable delay line architecture with five distinct output taps
• Single-channel configuration for precise timing control
• Surface-mount 8-SOIC packaging for compact integration

Applications

• Timing alignment in digital signal processing systems
• Pulse shaping and waveform generation circuits
• Clock distribution network synchronization

Procurement Notes

Verify the RoHS compliance status carefully, as the base model DS1040Z-D70 is listed as non-compliant while the plus suffix typically indicates compliance. Confirm availability through authorized distributors, noting that this component family may be subject to end-of-life restrictions or discontinuation notices from the manufacturer.

Selection Notes

Select this part when a fixed 70ns total delay with 10ns resolution is required. Ensure the design operates within the 4.75V to 5.25V voltage range and 0°C to 70°C temperature limits. Verify that the 8-SOIC footprint matches the PCB layout constraints and that single-channel functionality meets the system requirements.

Part Context

This component belongs to the DS1040 series of programmable delay lines. It shares the same functional block and pinout structure with variants like the DS1040Z-75+, differing primarily in total delay specifications and tap increments. The series is designed for applications requiring precise, adjustable time delays in high-speed digital interfaces.

Replacement Considerations

The DS1040Z-75+ is a documented alternative within the same series, offering 75ns total delay with 15ns tap increments. Verify if the specific delay characteristics of the replacement are compatible with the original circuit design before substitution.
