DS1004Z-5+

Overview

The DS1004Z-5+ is a five-tap all-silicon delay line manufactured by Analog Devices Inc. (formerly Maxim Integrated/Dallas Semiconductor). It provides five delayed clock phases per input within an 8-pin SOIC package. The device features precise tap-to-tap nominal delays of 5 ns with tolerances of ±1.0 ns and ±1.75 ns over temperature and voltage. Input-to-tap 1 delay is nominally 5 ns, with subsequent taps providing cumulative delays up to 25 ns at Tap 5. It operates on a +5V supply with CMOS design and TTL compatibility.

Feature Summary

• All-silicon timing circuit providing five equally delayed clock phases per single input
• Precise leading and trailing edge accuracy preserves input symmetry across all outputs
• CMOS architecture designed for direct TTL compatibility without additional level shifting
• Capable of driving up to 10 LS loads per output tap

Applications

• Clock distribution networks requiring multiple phase-shifted signals from a single source
• Timing alignment in high-speed digital systems
• Pulse width modulation circuits requiring precise delay steps
• Synchronization logic in communication equipment

Procurement Notes

Verify the component marking against the official datasheet specifications to confirm authenticity. Ensure the ordering suffix matches the required tolerance class (+ suffix indicates lead-free/RoHS compliance). Confirm the package type corresponds to the 150 mil 8-pin mini-SOIC format specified for the Z variant before finalizing procurement orders.

Selection Notes

Select this specific model when a 5 ns tap-to-tap delay is required. Compare the ±1.0 ns nominal tolerance against other variants like the DS1004Z-3 or DS1004Z-4 if tighter precision is needed. Verify that the 0°C to +70°C operating temperature range meets system requirements. Ensure the 5V supply voltage aligns with the target circuit design.

Part Context

The DS1004 series represents a family of high-speed silicon delay lines originally developed by Dallas Semiconductor. The Z suffix specifically denotes the 150 mil 8-pin mini-SOIC surface-mount package, distinguishing it from the DIP package variants. This component is part of a standardized lineup offering various delay increments to suit different timing applications.

Replacement Considerations

Direct replacements include DS1004M-5 for the DIP package equivalent. Other family members such as DS1004Z-2, DS1004Z-3, and DS1004Z-4 offer different tap-to-tap delays but share the same pinout and electrical characteristics.
