DS1010-125

Overview

The DS1010-125 is a 10-tap silicon delay line providing a total fixed delay of 125 ns with 12.5 ns per tap. It operates on a single 5V supply (4.75V to 5.25V) and features low-power CMOS technology compatible with TTL/CMOS logic levels. The device offers precise leading and trailing edge accuracy within ±5% or ±2 ns, whichever is greater. Available in standard 14-pin DIP or 16-pin SOIC packages, it supports commercial temperature ranges from 0°C to 70°C. Each tap can drive up to 10 LS-type loads.

Feature Summary

• Provides ten equally spaced output taps for precise timing control
• Ensures stable and accurate delays on both rising and falling edges
• Features low-power CMOS construction with TTL/CMOS compatibility
• Supports vapor phase, IR, and wave soldering processes

Applications

• Communications equipment timing synchronization
• Pulse width modulation circuits
• Digital signal processing timing adjustments
• Test and measurement instrumentation

Procurement Notes

Verify the specific package type required, as the DS1010 series is available in both 14-pin DIP and 16-pin SOIC configurations. Confirm that the operating environment remains within the specified commercial temperature range of 0°C to 70°C. Ensure power supply stability between 4.75V and 5.25V to maintain delay accuracy. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select the DS1010-125 when a fixed 125 ns total delay is required across ten distinct time steps. Consider the 16-pin SOIC package for surface mount applications requiring reduced board area, or the 14-pin DIP for through-hole mounting. Verify that the input pulse width meets the minimum requirements relative to the tap delay to ensure proper operation. Evaluate load capacitance limits to ensure each tap can drive the intended downstream logic gates effectively.

Part Context

The DS1010 series serves as an all-silicon alternative to older hybrid delay lines, offering improved economy and reliability. Manufactured by Maxim Integrated, now part of Analog Devices Inc., this component replaces discrete RC networks or complex digital counters for simple fixed-delay applications. The series includes various models ranging from 50 ns to 500 ns total delay, allowing designers to choose the exact timing resolution needed for their specific circuit requirements.

Replacement Considerations

Direct pin-compatible replacements include other DS1010 variants with different delay values, such as DS1010-100 or DS1010-150, provided the timing specifications match the design needs. For lead-free requirements, verify if a '+' suffix version is available from the manufacturer, though functional equivalence must be confirmed against the original datasheet parameters.
