DS1000Z-40N

Overview

The DS1000Z-40N is a tapped delay line integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It belongs to the DS1000Z series and is housed in an 8-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a working temperature range from 0°C to +70°C. It functions as a silicon delay line with five taps, providing precise timing delays for clock signals. The component is classified under Clock & Timer ICs and is currently marked as obsolete or discontinued.

Feature Summary

• Provides five distinct delayed clock phases per single input signal
• Maintains precise tap-to-tap nominal delay tolerances
• Features CMOS design compatible with TTL logic levels

Applications

• High-speed digital timing circuits requiring precise phase shifting
• Clock distribution networks needing multiple delayed phases
• Signal processing systems utilizing silicon delay lines

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance and specific suffix variations against original datasheets. Check for available surplus stock from certified distributors. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Selection Notes

Evaluate compatibility with existing system voltage levels between 4.75 V and 5.25 V. Consider the fixed delay characteristics versus programmable alternatives if flexibility is required. Assess thermal management needs within the 0°C to +70°C operating range. Verify package footprint compatibility with current PCB layout constraints.

Part Context

This component is part of the Maxim Integrated DS1000Z family of high-speed silicon delay lines. These devices are designed for applications requiring precise timing control without external components. The manufacturer has transitioned to Analog Devices Inc., affecting long-term support and documentation availability for legacy parts in this series.

Replacement Considerations

Check for direct pin-compatible substitutes within the DS1000Z series. Review Analog Devices recommended replacements for obsolete delay line products. Verify electrical parameter equivalence before substitution.
