DS1020S-25+

Overview

The DS1020S-25+ is a programmable 8-bit silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides 256 equal delay steps with an incremental delay of 0.25 ns and a step-zero delay of 10 ns, resulting in a maximum nominal delay of 73.75 ns. The device operates on a single +5V supply (4.75V to 5.25V) within a commercial temperature range of 0°C to 70°C. It supports both 3-wire serial and 8-bit parallel programming interfaces and is housed in a 16-pin SOIC package.

Feature Summary

• All-silicon CMOS architecture offering TTL/CMOS compatibility and low-power operation
• Programmable via 3-wire serial port or 8-bit parallel port for flexible timing control
• Features leading and trailing edge accuracy with auto-insertable, low-profile packaging

Applications

• Precision timing circuits requiring adjustable signal delays
• Pulse width modulation and digital pulse generation systems
• Test equipment and instrumentation utilizing programmable delay elements

Procurement Notes

Verify the specific suffix designation against official documentation to confirm package type and environmental rating. Confirm availability status as distribution channels may vary. Ensure the ordering information matches the required voltage and temperature specifications for the intended application environment.

Selection Notes

Select this model when a total delay range up to approximately 74 ns is required with fine resolution. Compare against other DS1020 variants based on specific step sizes ranging from 0.15 ns to 2 ns. Consider interface requirements for serial versus parallel programming when designing the system logic.

Part Context

This component belongs to the DS1020 family of programmable 8-bit silicon delay lines. The series includes models with varying step increments to accommodate different timing precision needs. The DS1020S variant specifically denotes the surface-mount SOIC package option within this product line.

Replacement Considerations

Direct substitutes include other DS1020 variants such as DS1020-15+, DS1020-50+, DS1020-100+, and DS1020-200+. Selection depends on matching the required delay step size and maximum delay time for the specific circuit design.
