DS1010S-125

Overview

The DS1010S-125 is a 10-tap all-silicon delay line manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-pin SOIC package. It provides a total delay of 125 ns with a tap increment of 12.5 ns. The device operates on a single 5V supply (4.75V to 5.25V) and features TTL/CMOS-compatible inputs. Each tap can drive up to 10 LS-type loads. The input pulse width must be at least 40% of the TAP 10 delay. Delay tolerance is specified as ±5% or ±2 ns, whichever is greater.

Feature Summary

• Provides ten equally spaced output taps for precise time delay applications
• Ensures equal precision for both leading and trailing edge delays
• Features low-power CMOS construction with standard logic compatibility
• Designed for auto-insertion and compatible with vapor phase, IR, and wave soldering

Applications

• Timing circuits requiring fixed signal propagation delays
• Pulse stretching and shaping networks
• Digital logic synchronization systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required delay value and package type. Check for RoHS compliance status if environmental regulations apply to the target assembly. Ensure storage conditions remain within specified limits to maintain reliability before installation.

Selection Notes

Select this model when a fixed 125 ns total delay is required across ten steps. Verify that the application voltage remains strictly between 4.75V and 5.25V. Ensure the input pulse width meets the minimum requirement relative to the total delay. Consider the 16-pin SOIC footprint constraints against available PCB space.

Part Context

This component belongs to the DS1010 series of silicon delay lines, which offers various total delay values ranging from 50 ns to 500 ns. The 'S' suffix indicates the surface-mount 16-pin SOIC package variant, while other suffixes may denote different delay increments or DIP packaging options within the same functional family.

Replacement Considerations

Direct pin-compatible replacements include other DS1010 variants with similar delay characteristics. Verify that any substitute maintains the 16-pin SOIC form factor and identical electrical specifications for supply voltage and load driving capability.
