DS1110S-250

Delay Lines IC Overview

The DS1110S-250 is a 10-tap silicon delay line from the DS1110 series, manufactured by Analog Devices Inc./Maxim Integrated. It provides ten equally spaced taps with a total fixed delay of 250ns and a per-tap increment of 25ns. The device operates on a single 5V supply (4.75V to 5.25V) within an industrial temperature range of -40°C to +85°C. Packaged in a standard 16-pin SOIC, it reproduces input logic states at each tap output after the specified delay intervals. The component features low-power CMOS technology and is TTL/CMOS compatible.

Delay Lines IC Feature Summary

• Provides ten equally spaced output taps for precise timing control
• Designed for equal precision in both leading-edge and trailing-edge delays
• Functions as a drop-in replacement for the legacy DS1010 model
• Capable of driving up to ten 74LS type loads per tap

Delay Lines IC Applications

• Communications Equipment
• Medical Devices
• Automated Test Equipment
• PC Peripheral Devices

Delay Lines IC Procurement Notes

Verify the specific package variant against design requirements, as the DS1110 series includes both TSSOP and SOIC options. Confirm that the 250ns total delay specification aligns with system timing constraints. Ensure power supply stability within the 4.75V to 5.25V range to maintain accuracy. Check for end-of-life status or obsolescence notices before finalizing procurement plans.

Delay Lines IC Selection Notes

Select this part when a fixed 250ns delay with ten intermediate sampling points is required. Compare against the DS1110E-250 if a smaller 14-pin TSSOP package is preferred over the 16-pin SOIC. Consider custom delay variants if the standard 25ns increments do not fit the application timeline. Verify load capacitance limits to ensure signal integrity across all ten outputs.

Delay Lines IC Part Context

The DS1110S-250 belongs to the DS1110 family of all-silicon delay lines, which serve as improved replacements for the older DS1010 series. This family offers various total delay values ranging from 50ns to 500ns. The 'S' suffix specifically denotes the 16-pin Small Outline package, distinguishing it from the 'E' suffix used for the 14-pin Thin Shrink Small Outline Package.

Delay Lines IC Replacement Considerations

The DS1110S-250 is designed as a direct drop-in replacement for the DS1010S-250. Designers upgrading from the DS1010 series can utilize this component without significant circuit modifications, provided the pinout compatibility is verified.
