DS1100U-20+T&R

Delay Lines IC Overview

The DS1100U-20+T&R is a five-tap silicon delay line from the DS1100 series, designed for surface-mount applications. It provides equally spaced timing taps with a nominal total delay of 20 nanoseconds. The device operates on a single +5V supply within a voltage range of 4.75V to 5.25V and functions across an industrial temperature range of -40°C to +85°C. Packaged in an 8-pin µMAX format, it features low-power CMOS technology compatible with TTL and CMOS logic levels. Each tap can drive up to ten 74LS loads, ensuring robust signal reproduction for both leading and trailing edges.

Delay Lines IC Feature Summary

• Provides five equally spaced output taps for precise timing control
• Reproduces input logic states with equal precision for rising and falling edges
• Compatible with standard TTL and CMOS logic families
• Supports vapor-phase, IR, and wave soldering processes

Delay Lines IC Applications

• Timing element generation in digital circuits
• Pulse width extension or compression
• Delay matching in high-speed data paths
• Replacement for legacy hybrid delay lines

Delay Lines IC Procurement Notes

Verify that the ordering suffix T&R confirms tape-and-reel packaging rather than tube packaging. Confirm the lead-free (+) designation aligns with RoHS compliance requirements. Ensure the specific 20ns delay variant matches the design timeline constraints. Validate the µMAX package footprint against the PCB layout specifications before finalizing procurement orders.

Delay Lines IC Selection Notes

Select this component when a fixed 20ns total delay with intermediate taps is required. Consider the 8-pin µMAX package for space-constrained designs. Verify that the 5V operating voltage matches the system power rails. Check if the industrial temperature range meets environmental requirements. Evaluate load capacitance limits to ensure signal integrity at the specified tap outputs.

Delay Lines IC Part Context

This part belongs to the DS1100 family of economy timing elements manufactured by Analog Devices / Maxim Integrated. The series offers various delay values ranging from 4ns to 500ns. The U suffix indicates the µMAX surface-mount package, while the Z suffix denotes the SOIC package. These devices serve as direct replacements for older hybrid delay technologies.

Delay Lines IC Replacement Considerations

The datasheet identifies the DS1100 series as an improved replacement for the DS1000. Designers should verify pin compatibility and electrical characteristics when transitioning from legacy components. Custom delay values are available upon request through manufacturer channels.
