DS1100LU-50/T&R

Delay Lines IC Overview

The DS1100LU-50/T&R is a 3.3V tapped delay line from the DS1100L series, manufactured by Analog Devices / Maxim Integrated. It provides five equally spaced taps with a nominal total delay of 50ns (Taps 1–5: 10ns, 20ns, 30ns, 40ns, 50ns). The device operates within a supply voltage range of 3.0V to 3.6V and supports an operating temperature range of -40°C to +85°C. Packaged in an 8-pin µMAX format, it features low-power CMOS technology with TTL/CMOS compatibility.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays
• Five equally spaced taps for flexible timing applications
• Low-power CMOS construction with high reliability

Delay Lines IC Applications

• Precision timing circuits requiring fixed delay intervals
• Digital signal processing synchronization
• Clock distribution network alignment

Delay Lines IC Procurement Notes

Verify the specific suffix 'T&R' indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors, as ordering suffixes may denote environmental compliance variations that do not alter functional performance.

Delay Lines IC Selection Notes

Select this component when a 50ns total delay with five intermediate taps is required at 3.3V. Ensure the application environment remains within the specified -40°C to +85°C temperature range. Verify that the load requirements per tap do not exceed the drive capability of ten 74LS loads.

Delay Lines IC Part Context

This part belongs to the DS1100L family, which serves as the 3.3V version of the standard DS1100 series. While other variants exist in SOIC packages, the LU designation specifically identifies the compact µMAX surface-mount package option designed to minimize PCB area usage.

Delay Lines IC Replacement Considerations

DS1100LU-50+ is a lead-free/RoHS-compliant variant of the same electrical specification. DS1100Z-50 is the 5V equivalent in an SOIC package. Cross-referencing requires verifying voltage tolerance and package footprint differences.
