DS1010-250

Overview

The DS1010-250 is a 10-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides ten equally spaced taps with a total delay of 250 ns and a per-tap increment of 25 ns. The device operates on a single 5V supply (4.75V to 5.25V) and features low-power CMOS technology compatible with TTL/CMOS logic levels. It offers high precision with leading and trailing edge accuracy within ±5% or ±2 ns, whichever is greater. Available in standard 14-pin DIP and 16-pin SOIC packages, it supports vapor phase, IR, and wave soldering methods.

Feature Summary

• Provides ten equally spaced output taps for precise time delay applications
• Ensures stable and accurate delays with matched leading and trailing edge performance
• Features low-power CMOS construction with TTL/CMOS-compatible input and output levels
• Supports multiple mounting options including auto-insertable 14-pin DIP and surface-mount 16-pin SOIC

Applications

• Timing circuits requiring fixed signal propagation delays
• Pulse width modulation and timing control systems
• Digital logic synchronization and clock distribution networks

Procurement Notes

Verify the specific package variant 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 0°C to 70°C temperature range. 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 DS1010-250 when a total delay of 250 ns with 25 ns tap increments is required. Consider the 16-pin SOIC package for surface mount applications to reduce PCB area, or the 14-pin DIP for through-hole compatibility with hybrid delay lines. Evaluate the load driving capability, as each tap can drive up to 10 LS-type loads. Verify that the input pulse width meets the minimum requirements for accurate delay measurement.

Part Context

The DS1010 series serves as an all-silicon alternative to older hybrid delay line technologies, offering improved economy and reliability. Manufactured originally by Dallas Semiconductor and later Maxim Integrated, now part of Analog Devices, these devices are designed for applications needing precise, fixed time delays without programmability. The series includes various delay values ranging from 50 ns to 500 ns.

Replacement Considerations

The DS1110E-250 is a related 10-tap silicon delay line from the same manufacturer family. While it shares similar functionality, verify pinout compatibility and package differences before substitution.
