DS1004Z-4+

Overview

The DS1004Z-4+ is a five-tap all-silicon delay line manufactured by Analog Devices Inc. (formerly Maxim Integrated). It operates on a single +5V supply within the range of 4.75V to 5.25V and functions across an operating temperature of 0°C to +70°C. The device provides precise tap-to-tap nominal delays of 1.5 ns with tolerances of ±1.0 ns, resulting in cumulative input-to-tap delays of 5 ns, 9 ns, 13 ns, 17 ns, and 21 ns for taps 1 through 5 respectively. Packaged in an 8-pin SOIC (150 mil), it features CMOS design with TTL compatibility and can drive up to 10 LS loads per output.

Feature Summary

• Provides five distinct delayed clock phases from a single input signal
• Maintains input symmetry through precise leading and trailing edge accuracy
• Compatible with standard 8-pin DIP and 150 mil 8-pin SOIC packages

Applications

• Timing circuit generation requiring multiple phase-shifted signals
• High-speed silicon delay applications preserving input waveform symmetry
• CMOS logic systems requiring TTL-compatible timing elements

Procurement Notes

Verify component authenticity against official datasheet specifications before integration. Confirm package type matches the 8-pin SOIC variant and validate electrical parameters against the required tolerance levels. Ensure environmental conditions remain within the specified 0°C to +70°C operational range during deployment.

Selection Notes

Select this model when specific cumulative delays of 5 ns, 9 ns, 13 ns, 17 ns, and 21 ns are required. Choose the Z suffix for surface-mount SOIC packaging instead of the M suffix for DIP. Ensure the application requires the ±1.0 ns tap-to-tap tolerance characteristic of the -4 variant rather than other delay steps.

Part Context

The DS1004 series represents a family of high-speed silicon delay lines designed for precise timing control. The Z-4 designation specifically identifies the surface-mount SOIC package with a 1.5 ns tap-to-tap delay step. This component belongs to the broader category of clock and timer ICs used for signal synchronization.

Replacement Considerations

DS1004M-4 serves as the direct pin-compatible alternative in an 8-pin DIP package. Other variants such as DS1004Z-2, DS1004Z-3, and DS1004Z-5 offer different tap-to-tap delay values but maintain identical physical footprints and electrical interfaces.
