DS1100U-50+

Delay Lines IC Overview

The DS1100U-50+ is a five-tap silicon delay line from the DS1100 series, housed in an 8-pin µMAX surface-mount package. It provides equally spaced taps with a nominal total delay of 50ns, distributed as 10ns per tap (Taps 1–5). The device operates on a single 5V supply within a range of 4.75V to 5.25V and functions across an industrial temperature range of -40°C to +85°C. It features low-power CMOS technology with TTL/CMOS compatibility, capable of driving up to ten 74LS loads per tap.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays over commercial and industrial temperature ranges
• Five equally spaced taps designed for equal precision in reproducing both leading and trailing edges
• Low-power CMOS construction compatible with TTL and CMOS logic families

Delay Lines IC Applications

• Timing element replacement for legacy DS1000 devices
• Precision pulse generation circuits requiring fixed delay intervals
• Synchronization applications in digital systems

Delay Lines IC Procurement Notes

Verify the specific ordering suffix to confirm package type and compliance status. The '+' suffix indicates a lead-free/RoHS-compliant package. Confirm availability through authorized distributors, as stock levels may vary. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Delay Lines IC Selection Notes

Select the DS1100U-50+ when a 50ns total delay with five intermediate taps is required in a compact surface-mount footprint. Compare against other DS1100 variants based on total delay requirements and package preferences. Verify that the 5V operating voltage aligns with the system power rails and that the load capacity meets the fan-out requirements of the connected logic gates.

Delay Lines IC Part Context

The DS1100 series comprises various delay lines offering total delays from 4ns to 500ns. The 'U' designation identifies the µMAX surface-mount package, while the 'Z' designation refers to the SO package. This component serves as a direct upgrade to older hybrid technologies, offering improved reliability and lower cost through monolithic silicon integration.

Delay Lines IC Replacement Considerations

The datasheet explicitly identifies the DS1100 series as an improved replacement for the DS1000. When substituting, verify pinout compatibility and ensure the new delay values meet the timing constraints of the original design.
