DS1100U-250+

Delay Lines IC Overview

The DS1100U-250+ 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 logic levels. 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 precision
• Designed as a low-cost, reliable all-silicon replacement for hybrid technologies
• Capable of driving up to ten 74LS loads per tap

Delay Lines IC Applications

• Timing element generation for digital circuits
• Signal synchronization and pulse stretching
• Replacement for legacy DS1000 series components

Delay Lines IC Procurement Notes

Verify that the ordering suffix matches the required specifications. The '+' suffix indicates a lead-free and RoHS-compliant package. Confirm the 'U' designation corresponds to the µMAX package type. Ensure the numeric portion aligns with the desired delay value. Check manufacturer documentation for any specific handling or storage requirements.

Delay Lines IC Selection Notes

Select this model when a fixed 250ns total delay with five intermediate taps is required. The µMAX package is suitable for space-constrained surface-mount designs. Verify that the system operates at +5V and requires TTL/CMOS compatible inputs. Consider the -250 variant if the specific 50ns step increments match the application needs.

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, indicated by the suffix number. The U variant specifically denotes the 8-pin µMAX surface-mount package, while the Z variant uses an SO package. All variants share identical electrical characteristics and functionality.

Delay Lines IC Replacement Considerations

The datasheet identifies the DS1100 series as an improved replacement for the DS1100Z-xxx and older DS1000 devices. Direct pin-compatible substitutes within the same family include other DS1100U-xxx models with different delay values.
