DS1100U-250/T&R

Delay Lines IC Overview

The DS1100U-250/T&R is a five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced timing taps with a nominal total delay of 250ns, resulting in individual tap delays of 50ns, 100ns, 150ns, 200ns, and 250ns. 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 TTL/CMOS-compatible inputs. The component is housed in an 8-pin µMAX surface-mount package and supports operation across the industrial temperature range of -40°C to +85°C.

Delay Lines IC Feature Summary

• Provides five equally spaced output taps for precise signal timing distribution
• Reproduces both leading and trailing edges with high accuracy
• Designed as a direct replacement for older hybrid DS1000 devices
• Compatible with vapor-phase, IR, and wave soldering processes

Delay Lines IC Applications

• Timing element generation in digital logic circuits
• Signal synchronization and pulse stretching applications
• Replacement for legacy discrete delay line components

Delay Lines IC Procurement Notes

Verify the specific suffix 'T&R' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status via the '+' designation if required. Check current availability as this series may be subject to discontinuation or limited stock constraints from distributors.

Delay Lines IC Selection Notes

Select the DS1100U variant specifically for its compact µMAX surface-mount footprint. Ensure the 250ns total delay aligns with system timing requirements. Verify that the 5V operating voltage matches the target circuit's power rails before implementation.

Delay Lines IC Part Context

This component belongs to the DS1100 family of all-silicon timing elements. The U suffix designates the 8-pin µMAX package type, while the Z suffix denotes the SOIC package. The numeric value indicates the total delay time in nanoseconds across the five taps.

Delay Lines IC Replacement Considerations

DS1000 series devices are explicitly cited as predecessors. Cross-reference with other DS1100 variants such as DS1100Z-250 for package differences.
