DS1100LU-100

Delay Lines IC Overview

The DS1100LU-100+ is a 3.3V, five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced output taps with a nominal total delay of 100ns, resulting in individual tap delays of 20ns, 40ns, 60ns, 80ns, and 100ns. 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. Packaged in an 8-pin µMAX format, it features low-power CMOS technology compatible with TTL and CMOS logic levels.

Delay Lines IC Procurement Notes

Verify the specific suffix against official documentation to confirm package type and compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the ordering code matches the required delay value and temperature range specifications before finalizing procurement orders.

Delay Lines IC Selection Notes

Select this component when a fixed 100ns total delay with five intermediate taps is required in a surface-mount design. Consider the 3.3V supply requirement and ensure the load does not exceed ten 74LS loads per tap. Verify that the µMAX package dimensions fit the target PCB layout constraints.

Delay Lines IC Part Context

This part belongs to the DS1100L series, which represents the 3.3V version of the standard DS1100 family. While the original DS1100 operated at 5V, the L-series variants are optimized for lower voltage applications while maintaining similar performance characteristics and pinout compatibility.

Delay Lines IC FAQ

What is the delay tolerance for the DS1100LU-100+?

For delays greater than 40ns, the input-to-tap delay tolerance is specified as -13% to +13% over the industrial temperature range (-40°C to +85°C).

How many loads can each tap drive?

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

Is the DS1100LU-100+ lead-free?

Yes, parts with the '+' suffix in the part number denote a lead(Pb)-free/RoHS-compliant package.
