DS1110S-125

Delay Lines IC Overview

The DS1110S-125 is a 10-tap silicon delay line from the DS1110 series, designed as an improved replacement for the DS1010. It provides ten equally spaced taps with a total fixed delay of 125ns and a per-tap delay of 12.5ns. 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. Each tap can drive up to ten 74LS type loads. The component is housed in a standard 16-pin SO package and supports vapor phase, IR, and wave soldering processes.

Delay Lines IC Feature Summary

• Provides ten equally spaced output taps for precise signal timing control
• Designed for equal precision in both leading-edge and trailing-edge delays
• Compatible with standard surface-mount assembly methods including wave soldering

Delay Lines IC Applications

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

Delay Lines IC Procurement Notes

Verify the specific suffix 'S' confirms the 16-pin SO package variant rather than the TSSOP option. Confirm the '-125' designation matches the required 125ns total delay specification. Check current availability status as this component may be subject to lifecycle changes or discontinuation by the manufacturer.

Delay Lines IC Selection Notes

Select this part when a fixed 125ns propagation delay is required across ten distinct output stages. Ensure the system voltage remains within the 4.75V to 5.25V range for optimal accuracy. Consider the 16-pin SO footprint constraints during PCB layout design compared to the alternative TSSOP package options available in the same family.

Delay Lines IC Part Context

This component belongs to the DS1110 family of all-silicon delay lines manufactured by Analog Devices Inc./Maxim Integrated. It serves as a direct drop-in replacement for the legacy DS1010 model while offering improved stability and precision. The series covers various delay values ranging from 5ns to 500ns, allowing designers to select specific timing characteristics without custom fabrication.

Delay Lines IC Replacement Considerations

The DS1110E-125 is the pin-compatible alternative using a 14-pin TSSOP package instead of the 16-pin SO form factor. Both variants share identical electrical specifications and functionality.
