DS1023S-25+T

Overview

The DS1023S-25+T is an 8-bit programmable timing element manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 5V supply (4.75V to 5.25V) and features a delay step size of 0.25 ns. The device provides a maximum delay of 63.75 ns relative to the reference output, with a typical step zero delay of 16.5 ns. It supports both parallel and serial programming modes via dedicated control pins. The component is housed in a 16-pin SOIC package and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Configurable as a delay line, pulse width modulator, or free-running oscillator
• Includes an on-chip reference delay to compensate for inherent step zero delay
• Supports both parallel and serial programming interfaces
• Capable of delaying clocks by a full period or more

Applications

• Clock phase control applications requiring precise timing adjustments
• Pulse width modulation signal generation
• Free-running oscillator circuits using external feedback connections

Procurement Notes

Verify the specific suffix '+T' indicates tape and reel packaging when sourcing components. Confirm that the manufacturer designation matches Analog Devices Inc. or Maxim Integrated to ensure authenticity. Check RoHS compliance status against current environmental regulations before finalizing procurement orders.

Selection Notes

Select this model when a total delay range of approximately 63.75 ns is required. Ensure the application can accommodate the 0.25 ns resolution provided by this specific variant. Verify that the 16-SOIC package dimensions fit the available PCB space constraints.

Part Context

This component belongs to the DS1023 family of 8-bit programmable timing elements. Other variants in the series include models with different step sizes such as 0.5 ns, 1 ns, 2 ns, and 5 ns, offering varying maximum delay ranges from 127.5 ns up to 1275 ns depending on the specific part number selected.

Replacement Considerations

DS1023S-50+T offers a 0.5 ns step size. DS1023S-100+T provides a 1 ns step size. DS1023S-200+T utilizes a 2 ns step size. DS1023S-500+T features a 5 ns step size. All share identical pinouts and functionality.
