DS1045S-4+

Overview

The DS1045S-4+ 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 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 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
• Offers precise leading and trailing edge accuracy for pulse reproduction
• Configurable via four dedicated input pins for flexible timing control

Applications

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

Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as availability varies by region. Confirm RoHS compliance status and lead times through authorized distributors. Ensure the specific variant matches the required delay increment specifications for the target application.

Selection Notes

Select this component when fixed 4 ns resolution delay steps are required between 9 ns and 84 ns. Compare against other family members offering 3 ns or 5 ns increments if different timing granularity is needed. Verify package compatibility and operating temperature ranges before integration into the design.

Part Context

This part belongs to the DS1045 series of programmable delay lines. The 'S' indicates a surface-mount SOIC-16 package, while the '-4' specifies the 4 ns delay increment characteristic. It is distinct from the DS1040 programmable one-shot generator within the same product family.

Replacement Considerations

Direct substitutes include DS1045S-3+ for 3 ns increments and DS1045S-5+ for 5 ns increments. These parts share identical pinouts and packaging but differ in delay step resolution. Verify functional equivalence regarding power consumption and electrical characteristics.
