DS1100LU-75+

Delay Lines IC Overview

The DS1100LU-75+ is a 3.3V silicon delay line manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-pin µMAX package. It provides five equally spaced taps with a nominal total delay of 75ns. The device operates within a supply voltage range of 3.0V to 3.6V and supports an operating temperature range from -40°C to +85°C. Key electrical parameters include an active current of 10mA at maximum voltage and 1MHz frequency, output rise/fall times of 2.0ns to 2.5ns, and input capacitance of 5pF to 10pF. Input pulse width must be at least 20% of the Tap 5 delay.

Delay Lines IC Procurement Notes

Verify the specific ordering suffix to confirm package type and compliance status. The '+' suffix indicates a lead-free/RoHS-compliant package. Ensure the selected variant matches the required thermal and electrical specifications for your application environment. Cross-reference part numbers carefully as different suffixes may denote tape-and-reel packaging or non-compliant versions.

Delay Lines IC Selection Notes

Select the DS1100LU-75+ when a fixed 75ns total delay with five intermediate taps is required. Consider the µMAX package for surface-mount applications requiring space savings. Verify that the input pulse width meets the minimum requirement relative to the total delay. Evaluate power consumption constraints, as active current reaches 10mA at peak frequencies.

Delay Lines IC Part Context

The DS1100L series serves as a 3.3V version of the original DS1100 family. It utilizes industry-standard µMAX and SO packaging to replace hybrid delay line technologies. The series offers customizable delays and fast-turn prototypes, positioning it as a cost-effective solution for precision timing needs in commercial and industrial environments.

Delay Lines IC Replacement Considerations

Direct replacements include other variants within the DS1100L series with different delay values (e.g., DS1100LU-30+, DS1100LU-100+) or package types (DS1100LZ-75+). Verify pin compatibility and electrical characteristics before substitution.

Delay Lines IC FAQ

What is the difference between the DS1100LU-75+ and DS1100LU-75?

The '+' suffix denotes a lead-free/RoHS-compliant package, whereas the non-plus version may contain lead.

How does the delay tolerance vary with temperature?

For delays greater than 40ns, the tolerance ranges from -5% to +5% at +25°C, widening to -13% to +13% across the full -40°C to +85°C operating range.

Can the DS1100LU-75+ drive standard logic loads?

Yes, each tap is capable of driving up to 10 LS loads.
