DS1100U-300/T&R

Delay Lines IC Overview

The DS1100U-300/T&R is a five-tap silicon delay line from the DS1100 series, manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced timing taps with a nominal total delay of 300ns, resulting in individual tap delays of 60ns, 120ns, 180ns, 240ns, and 300ns. The device operates on a single 5V supply within a voltage range of 4.75V to 5.25V. It utilizes low-power CMOS technology and features an 8-pin µMAX surface-mount package. The component supports industrial temperature operation from -40°C to +85°C and includes tape-and-reel packaging for automated assembly.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays over commercial and industrial temperature ranges
• Five equally spaced taps that reproduce both leading and trailing edges with equal precision
• Low-power CMOS construction compatible with TTL and standard logic loads

Delay Lines IC Applications

• Timing element replacement for legacy DS1000 devices
• Precision pulse generation circuits requiring fixed delay intervals
• Digital signal processing synchronization tasks

Delay Lines IC Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel configuration. Ensure the part number matches the required delay value and operating temperature range. Confirm RoHS compliance status if lead-free components are mandated for the assembly process. Cross-reference the manufacturer's latest documentation for any potential obsolescence notices or alternate sourcing options.

Delay Lines IC Selection Notes

Select this component when a fixed 300ns total delay with five intermediate taps is required. The µMAX package is suitable for space-constrained printed circuit board designs. Verify that the system power supply remains within the 4.75V to 5.25V range to maintain specified electrical characteristics. Consider the drive capability of each tap, which supports up to ten 74LS loads, when designing the output stage.

Delay Lines IC Part Context

This component belongs to the DS1100 series of economy timing elements. The series offers various delay values ranging from 4ns to 500ns, distinguished by the numeric suffix in the part number. The 'U' designation indicates the 8-pin µMAX surface-mount package, while the '/T&R' suffix specifies tape-and-reel packaging for high-volume manufacturing integration.

Delay Lines IC Replacement Considerations

The datasheet identifies the DS1100 as an improved replacement for the DS1000 series. Engineers replacing older discrete delay lines should verify pin compatibility and ensure the new silicon-based solution meets the required delay tolerance specifications.
