DS1040Z-B40+

Overview

The DS1040Z-B40+ 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 delay of 40ns, with subsequent taps incrementing by 50ns each. The device operates on a single 5V supply voltage ranging from 4.75V to 5.25V. It is housed in an 8-SOIC package with a width of 3.90mm and supports surface mount installation. The component functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Programmable delay architecture allowing precise timing adjustments via five distinct output taps.
• Single emitter configuration simplifies circuit design for point-to-point signal distribution.
• Fixed incremental step size ensures consistent delay spacing between adjacent taps.

Applications

• Timing alignment in digital communication systems
• Pulse shaping and waveform generation circuits
• Clock skew compensation in high-speed data interfaces

Procurement Notes

Verify the specific suffix B40 against official datasheets to confirm the initial tap delay value differs from standard variants. Confirm RoHS compliance status as manufacturing sources may vary. Check for obsolescence notices since Maxim Integrated products are now under Analog Devices management. Ensure the 8-SOIC footprint matches the target PCB layout constraints before ordering.

Selection Notes

Select this component when a fixed 250ns total delay range is required with a specific 40ns starting offset. Compare against other DS1040 variants if different initial tap delays or packaging options are needed. Verify that the 5V logic levels and SOIC package dimensions fit the system requirements. Consider thermal dissipation capabilities within the 0°C to 70°C operating range for the intended environment.

Part Context

This part belongs to the DS1040 family of programmable delay lines, which are designed for precise time-delay applications. The Z suffix indicates RoHS compliance, while the B40 suffix specifies the unique tap configuration starting at 40ns. These devices are commonly used in timing-critical analog and digital signal processing applications requiring stable and accurate delay steps.

Replacement Considerations

Direct substitutes include other DS1040 variants with similar total delay but different tap configurations. Verify pin compatibility and electrical specifications before swapping. No officially confirmed direct replacement part numbers are publicly documented for this specific suffix combination.
