DS1045S-4/T&R

Overview

The DS1045S-4/T&R is a programmable silicon delay line manufactured by Analog Devices Inc. under the Maxim Integrated brand. 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 4 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 a 16-pin SOIC package.

Feature Summary

• All-silicon time delay mechanism providing both leading and trailing edge accuracy
• Single input drives two independent 4-bit programmable outputs
• Low-power CMOS design compatible with TTL logic levels

Applications

• Timing alignment in digital signal processing systems
• Pulse width modulation generation
• Clock skew compensation in high-speed interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific tape-and-reel packaging specifications prior to procurement. Ensure storage conditions meet moisture sensitivity level requirements to maintain device integrity during assembly processes.

Selection Notes

Select this model when a fixed 4 ns delay increment is required between 9 ns and 84 ns. Compare against DS1045S-3 and DS1045S-5 variants if different step sizes are needed. Verify that the 16-pin SOIC package fits the target PCB footprint and that the 5V operating voltage aligns with the system power rails.

Part Context

This component belongs to the DS1045 family of programmable delay lines, originally developed by Dallas Semiconductor and later acquired by Maxim Integrated, now part of Analog Devices. The 'S' suffix denotes the surface-mount SOIC package variant, while '-4' specifies the 4 nanosecond delay increment characteristic unique to this member of the series.

Replacement Considerations

Direct functional substitutes include DS1045S-3 and DS1045S-5 for identical packages with different delay steps. Cross-reference DS1045S-10 for custom increment options. Verify pinout compatibility and electrical characteristics before substituting any alternative delay line components.
