DS1040Z-D70

Overview

The DS1040Z-D70 is a single-channel programmable delay line integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides a total available delay of 70ns distributed across five taps. The first tap offers a fixed delay of 30ns, with subsequent taps incrementing by 10ns each. The device operates on a single 5V supply voltage ranging from 4.75V to 5.25V. It is housed in an 8-SOIC surface-mount package with a width of 3.90mm. The component supports operation within a commercial temperature range of 0°C to 70°C and is classified as obsolete.

Feature Summary

• Single-emitter programmable architecture for precise timing control
• Five-tap output structure allowing flexible delay distribution
• Fixed initial tap delay combined with uniform incremental steps

Applications

• Clock signal skew compensation in digital systems
• Pulse width adjustment in timing circuits
• Data alignment in high-speed serial interfaces

Procurement Notes

Verify component obsolescence status prior to integration into new designs. Confirm RoHS compliance requirements against the specific manufacturing batch, as this variant may not meet current environmental standards. Validate package dimensions and pinout compatibility during PCB layout finalization to ensure mechanical fit within the target enclosure constraints.

Selection Notes

Select alternative models from the DS1040 family if different total delay values or tap increments are required. Consider the DS1040Z-75+ or DS1040Z-250+ for varying delay ranges. Ensure the 8-SOIC package footprint matches existing board space limitations. Verify that the 5V logic levels align with the system's power domain and interface requirements.

Part Context

This component belongs to the DS1040 series of programmable delay lines. The suffix D70 specifically denotes the 70ns total delay configuration. Other variants in the series offer different delay totals such as 75ns or 250ns. All members share similar architectural features including the five-tap structure and SOIC packaging options.

Replacement Considerations

Public confirmed substitute part numbers include DS1040Z-75+ and DS1040Z-250+. These alternatives maintain the same package type and functional architecture while offering different delay characteristics.
