DS1100LU-20/T&R

Delay Lines IC Overview

The DS1100LU-20/T&R is a 3.3V tapped delay line from the DS1100L series, housed in an 8-pin µMAX surface-mount package. It provides five equally spaced output taps with a nominal total delay of 20ns (Taps 1–5: 4ns, 8ns, 12ns, 16ns, 20ns). The device operates on a supply voltage between 3.0V and 3.6V, drawing 10mA at 1MHz. It supports input pulse widths as low as 20% of Tap 5 delay and features TTL/CMOS compatibility. Operating temperatures range from -40°C to +85°C.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays across all taps
• Low-power CMOS technology compatible with both TTL and CMOS logic levels
• Designed for equal precision reproduction of both leading and trailing signal edges

Delay Lines IC Applications

• Timing element generation for digital logic circuits
• Signal synchronization and phase alignment tasks
• Delay line implementation in communication systems

Delay Lines IC Procurement Notes

Verify that the specific suffix /T&R corresponds to tape-and-reel packaging when sourcing components. Confirm RoHS compliance status via the manufacturer's official documentation or datasheet revision history. Ensure the ordering part number matches the required delay specification and package type before finalizing procurement orders.

Delay Lines IC Selection Notes

Select this component when a fixed 20ns total delay with five intermediate taps is required within a 3.3V system. Verify that the 10mA active current consumption fits the power budget. Ensure the application environment remains within the specified -40°C to +85°C temperature range for guaranteed performance.

Delay Lines IC Part Context

This component belongs to the DS1100L family of 3.3V economy timing elements. It serves as a silicon-based alternative to hybrid delay lines, offering superior reliability and reduced PCB area through its compact µMAX package design.

Delay Lines IC Replacement Considerations

DS1100LU-20+ is the lead-free variant of the same electrical specification. DS1100Z-20+ offers identical functionality but utilizes an SOIC-8 package instead of µMAX.
