DS1100U-300+

Delay Lines IC Overview

The DS1100U-300+ is a five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced taps with a nominal total delay of 300ns, resulting in individual tap delays of 60ns, 120ns, 180ns, 240ns, and 300ns. The device operates on a single +5V supply within a 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

• All-silicon timing circuit providing stable and precise delays for both leading and trailing edges
• Five equally spaced taps capable of driving up to 10 standard 74LS loads
• Low-power CMOS design compatible with TTL and CMOS logic families

Delay Lines IC Applications

• Timing element applications requiring fixed signal propagation delays
• Replacement for legacy DS1000 hybrid delay lines
• Circuit synchronization and pulse stretching

Delay Lines IC Procurement Notes

Verify that the ordering suffix matches the required package type and compliance status. The plus sign indicates a lead-free and RoHS-compliant package. Confirm the specific delay value corresponds to the numeric portion of the part number. Ensure the supplier source is authorized to prevent counterfeit components.

Delay Lines IC Selection Notes

Select this model when a total delay of 300ns is required across five evenly distributed output points. Verify that the system power supply remains strictly between 4.75V and 5.25V. Consider the µMAX package dimensions if PCB space is constrained. Check input pulse width requirements against the minimum specification to ensure accurate delay tolerance.

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, distinguished by the numeric suffix. 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 pinouts.

Delay Lines IC Replacement Considerations

The datasheet identifies the DS1100 as an improved replacement for the DS1000. Designers replacing older hybrid technologies should verify that the new silicon delay line meets the specific timing precision and load-driving requirements of the original circuit.
