DS1004Z-2

Overview

The DS1004Z-2 is a five-tap all-silicon delay line manufactured by Maxim Integrated (formerly Dallas Semiconductor). It provides precise timing delays in an 8-pin SOIC package. The device features a nominal input-to-tap 1 delay of 5 ns, with subsequent taps delayed by 2 ns intervals. Nominal tap-to-tap tolerances are ±0.75 ns at +25°C and ±1.5 ns over the operating temperature range of 0°C to +70°C. 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 input
• Precise leading and trailing edge accuracy preserves input symmetry
• CMOS design with TTL compatibility for standard logic integration
• Capable of driving up to 10 LS loads per output

Applications

• Clock phase generation for high-speed digital systems
• Timing alignment in signal processing circuits
• Precision delay applications requiring symmetric edges

Procurement Notes

Verify the manufacturer origin, as the component was originally produced by Dallas Semiconductor before its acquisition by Maxim Integrated. Confirm the specific suffix 'Z' indicates the 150 mil 8-pin SOIC package variant. Ensure compliance with RoHS directives if required for the target application, noting that original datasheets may list non-compliance depending on the production era.

Selection Notes

Select the DS1004Z-2 when a 2 ns tap-to-tap delay is required within the DS1004 family. Compare against other suffixes (-3, -4, -5) which offer different nominal delay increments. Verify that the 8-pin SOIC package meets the board space requirements compared to the DIP option. Ensure the system operates within the specified voltage and temperature ranges to maintain delay accuracy.

Part Context

The DS1004 series represents a family of high-speed silicon delay lines designed for precision timing applications. The Z suffix specifically denotes the surface-mount 8-pin SOIC package, while the M suffix indicates the through-hole DIP package. This part is part of a standardized lineup offering various delay steps to accommodate different system timing requirements.

Replacement Considerations

Direct replacements include other members of the DS1004 family such as DS1004Z-3, DS1004Z-4, or DS1004Z-5, provided the delay values match the application needs. Cross-referencing with Maxim Integrated's current portfolio is recommended to identify any updated equivalents.
