DS1100Z-20

Delay Lines IC Overview

The DS1100Z-20 is a five-tap economy timing element manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced delays from 4ns to 500ns, with the -20 suffix indicating a total delay of 20ns across five taps. The device operates on a single +5V supply within a range of 4.75V to 5.25V and features low-power CMOS technology compatible with TTL/CMOS logic levels. Packaged in an 8-pin SOIC (SO) surface-mount format, it supports industrial temperature ranges from -40°C to +85°C. Each tap can drive up to 10 standard 74LS loads.

Delay Lines IC Procurement Notes

Verify the specific package variant and RoHS compliance status when sourcing. Confirm that the operating voltage remains within the specified 4.75V to 5.25V range during integration. Ensure thermal management aligns with the industrial temperature rating of -40°C to +85°C for reliable performance.

Delay Lines IC Selection Notes

Select this component when a fixed 20ns total delay with five intermediate taps is required. Consider the 8-pin SOIC package for surface-mount assembly constraints. Evaluate the low-power CMOS characteristics against system power budgets and ensure TTL/CMOS compatibility with existing logic families.

Delay Lines IC Part Context

The DS1100 series consists of silicon delay lines designed as improved replacements for older DS1000 models. The Z suffix denotes the 8-pin SOIC package option, while the numeric suffix indicates the total delay value. This family offers cost-effective alternatives to hybrid technologies with superior reliability.

Delay Lines IC Replacement Considerations

DS1000 series devices are noted as predecessors. Verify pinout compatibility and electrical specifications before substitution. Custom delay values may be available through manufacturer channels if standard increments do not meet design requirements.

Delay Lines IC FAQ

What is the delay tolerance for the DS1100Z-20?

For delays less than or equal to 40ns, the input-to-tap delay tolerance is ±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 DS1100Z-20 lead-free?

Yes, the '+' suffix in the part number (e.g., DS1100Z-20+) indicates a lead-free/RoHS-compliant package.
