DS1100Z-20+

Delay Lines IC Overview

The DS1100Z-20+ is a five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced taps with a total nominal delay of 20ns, where individual tap delays range from 4ns to 20ns. The device operates on a single 5V supply (4.75V to 5.25V) and features TTL/CMOS-compatible logic levels. It is housed in an 8-pin SO package and supports operation across an industrial temperature range of -40°C to +85°C.

Delay Lines IC Procurement Notes

Verify the component status as discontinued or limited availability through official manufacturer channels. Confirm RoHS compliance and lead-free packaging specifications before procurement. Ensure the specific suffix matches the required tape-and-reel or tube packaging format for your assembly process.

Delay Lines IC Selection Notes

Select this model when a fixed 20ns total delay with five intermediate steps is required. Consider the 8-pin SO package for surface-mount applications. Verify that the 5V operating voltage aligns with your system power rails and that the TTL/CMOS compatibility meets your interface requirements.

Delay Lines IC Part Context

This component belongs to the DS1100 series of economy timing elements. It serves as an improved replacement for older hybrid technology delay lines like the DS1000. The series offers various delay values and package options to accommodate different PCB area and timing precision needs.

Delay Lines IC Replacement Considerations

The datasheet identifies the DS1100 series as an improved replacement for the DS1000. Verify pinout compatibility and electrical characteristics when substituting legacy components.

Delay Lines IC FAQ

What is the tolerance of the delay times?

For delays less than or equal to 40ns, the input-to-tap delay tolerance is specified as ±2ns at +25°C, ±3ns over 0°C to +70°C, and ±4ns over -40°C to +85°C.

How many loads can each tap drive?

Each tap can drive up to 10 standard 74LS loads.

Is the delay programmable?

No, the DS1100Z-20+ is a non-programmable delay line with fixed tap intervals determined by the part number.
