DS1100LU-50+

Delay Lines IC Overview

The DS1100LU-50+ is a 3.3V, all-silicon 5-tap delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides five equally spaced output taps with a nominal total delay of 50ns (Taps 1–5: 10ns, 20ns, 30ns, 40ns, 50ns). The device operates within a supply voltage range of 3.0V to 3.6V and features low-power CMOS technology compatible with TTL and CMOS logic levels. Packaged in an 8-pin µMAX format, it supports operation across the industrial temperature range of -40°C to +85°C.

Delay Lines IC Feature Summary

• Replacement for hybrid delay line technologies

Delay Lines IC Procurement Notes

Verify that the component matches the specified 8-pin µMAX package and lead-free/RoHS-compliant status indicated by the '+' suffix. Confirm the operating temperature range requirements align with the industrial specification (-40°C to +85°C) before finalizing procurement orders.

Delay Lines IC Selection Notes

Select this model when a fixed 50ns total delay with five intermediate taps is required at 3.3V. Ensure the application does not exceed the maximum input pulse width or frequency limits defined in the AC electrical characteristics table. Consider the SOIC variant if surface-mount footprint constraints differ from the µMAX outline.

Delay Lines IC Part Context

This component belongs to the DS1100L series, which serves as the 3.3V version of the standard 5V DS1100 family. The 'LU' designation specifically identifies the 8-pin µMAX surface-mount package, while the '-50' suffix defines the 50ns nominal delay characteristic across the five taps.

Delay Lines IC FAQ

What are the nominal delay values for each tap?

For the DS1100LU-50+, the nominal delays are 10ns, 20ns, 30ns, 40ns, and 50ns for Taps 1 through 5, respectively.

How many loads can each tap drive?

Each tap is capable of driving up to ten 74LS loads.

Is the delay tolerance affected by temperature?

Yes, the input-to-tap delay tolerance varies with temperature; for delays greater than 40ns, the tolerance ranges from -5% to +5% at +25°C to -13% to +13% at -40°C to +85°C.
