DS1100M-40

Delay Lines IC Overview

The DS1100M-40 is a five-tap silicon delay line designed for precise timing applications. It provides equally spaced taps with a total nominal delay of 40ns, where individual tap delays range from 8ns to 40ns. The device operates on a single 5V supply within a voltage range of 4.75V to 5.25V. It features low-power CMOS technology and is TTL/CMOS compatible. Each tap can drive up to ten 74LS loads. The component is housed in an 8-pin PDIP package and supports through-hole mounting. It functions reliably across an industrial temperature range of -40°C to +85°C.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays over commercial and industrial temperature ranges
• Five equally spaced taps that reproduce both leading and trailing edges with equal precision
• Low-power CMOS construction with TTL/CMOS-compatible logic levels

Delay Lines IC Applications

• Timing element generation for digital circuits

• Pulse width extension or compression in signal processing

Delay Lines IC Procurement Notes

Verify the exact suffix designation when sourcing, as it indicates package type and compliance status. Confirm availability status, as this component may be discontinued or subject to limited supply constraints depending on the distributor. Ensure the selected variant matches the required operating temperature range and pin configuration for your specific PCB layout.

Delay Lines IC Selection Notes

Select the DS1100M-40 when a fixed 40ns total delay with five intermediate steps is required. Consider the PDIP package for through-hole assembly needs. Evaluate if the 5V operation aligns with your system power rails. For surface-mount requirements, alternative packages such as µMAX or SO are available within the same series but require different footprints.

Delay Lines IC Part Context

This component belongs to the DS1100 series of economy timing elements manufactured by Analog Devices / Maxim Integrated. The series offers various delay values ranging from 20ns to 500ns. The DS1100 series serves as a replacement for older hybrid technology delay lines, offering improved reliability and lower cost through monolithic silicon design.

Delay Lines IC Replacement Considerations

The datasheet identifies the DS1100 series as an improved replacement for the DS1000. Verify pin compatibility and electrical characteristics before substituting other delay line components.
