DS1045S-3+

Overview

The DS1045S-3+ is a programmable silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It features one input and two 4-bit programmable delay outputs, allowing for 16 selectable delay values per output. The device provides uniform delay increments of 3 ns, with a minimum inherent delay of 9 ns and a maximum achievable delay of 84 ns. It operates within a supply voltage range of 4.75 V to 5.25 V and supports surface mount installation in an SOIC-16 package. The component functions as a low-power CMOS design that is TTL-compatible.

Feature Summary

• Generates two independent programmable delay outputs from a single input signal
• Allows precise delay adjustment via four dedicated input pins
• Maintains accuracy on both leading and trailing edges of the output pulse

Applications

• Timing alignment in digital communication systems
• Pulse width modulation circuitry
• Clock skew compensation in high-speed data interfaces

Procurement Notes

Verify current availability status as this component may be discontinued or subject to limited supply constraints. Confirm package integrity and RoHS compliance upon receipt. Cross-reference part numbers carefully to ensure the specific suffix matches required specifications. Consult official distributor channels for accurate lead times and stock levels prior to procurement planning.

Selection Notes

Select this model when a fixed 3 ns delay increment is required. Ensure the application voltage aligns with the 5 V standard. Verify that the SOIC-16 package fits the PCB layout. Consider thermal limits if operating near the upper temperature boundary. Compare against other family members if different delay steps are needed.

Part Context

This component belongs to the DS1045 series of programmable delay lines. The 'S' suffix indicates the SOIC-16 surface mount package variant. The '+3' designation specifies the 3 ns delay increment characteristic. This series is designed for applications requiring precise, adjustable time delays without external timing components.

Replacement Considerations

Check for direct substitutes within the DS1045 family such as DS1045S-4 or DS1045S-5 if different delay increments are acceptable. Verify pin compatibility and package dimensions before substitution. Ensure electrical parameters like supply voltage and propagation delay match the original design requirements.
