DS1040Z-250+

Overview

The DS1040Z-250+ is a single-emitter programmable delay line IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a total available delay of 250ns distributed across five taps. The first tap offers a fixed delay of 50ns, with subsequent taps incrementing by 50ns each. The device operates on a single 5V supply within the range of 4.75V to 5.25V. It is housed in an 8-SOIC package (3.90mm wide) and supports surface mount installation. The component functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Programmable delay line architecture with five distinct output taps
• Single emitter configuration for signal timing control
• Fixed initial tap delay with uniform incremental steps
• Standard 8-pin surface mount packaging

Applications

• Signal synchronization in digital circuits
• Timing adjustment in data transmission systems
• Pulse width modulation applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status and check for obsolescence notices, as this part may be discontinued. Ensure the specific suffix matches required specifications before procurement.

Selection Notes

Select this component when a fixed 250ns total delay with five programmable outputs is required. Verify that the 5V operating voltage aligns with system power rails. Consider the 8-SOIC package dimensions for PCB layout compatibility and ensure the commercial temperature range meets environmental requirements.

Part Context

This part belongs to the DS1040 family of delay lines from Maxim Integrated, now part of Analog Devices. These devices are designed for precise timing adjustments in electronic systems. The DS1040 series typically offers configurable delay steps, making them suitable for applications requiring accurate signal propagation control without external discrete components.

Replacement Considerations

Check for official replacement parts listed in Analog Devices documentation. Verify pinout compatibility and electrical parameters if considering cross-brand alternatives. Confirm package dimensions match existing footprints.
