DS1100LZ-20/T&R

Delay Lines IC Overview

The DS1100LZ-20/T&R is a 3.3V, all-silicon tapped delay line from the DS1100L series, manufactured by Analog Devices Inc./Maxim Integrated. It provides five equally spaced taps with a total nominal delay of 20ns. The device operates within a supply voltage range of 3.0V to 3.6V and supports an industrial temperature range of -40°C to +85°C. Packaged in an 8-pin SOIC format and supplied in tape-and-reel configuration, it reproduces input logic states at outputs after fixed delays. Each tap can drive up to ten 74LS loads, ensuring TTL/CMOS compatibility.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays
• Five equally spaced taps for flexible timing applications
• Low-power CMOS technology with TTL/CMOS compatibility
• Accurate reproduction of both leading and trailing edges

Delay Lines IC Applications

• Timing element replacement for hybrid technologies
• Fast-turn prototypes requiring custom or standard delays
• Digital signal processing synchronization circuits

Delay Lines IC Procurement Notes

Verify the specific suffix T&R confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the lead-free designation aligns with environmental compliance standards for your manufacturing line. Ensure the ordering code matches the exact 20ns delay specification needed for the design.

Delay Lines IC Selection Notes

Select this component when a 3.3V supply is available and surface-mount packaging is preferred over DIP options. The 20ns total delay suits applications requiring shorter timing intervals compared to higher-value variants. Verify that the 8-pin SO package footprint fits the PCB layout constraints and that the industrial temperature rating meets operational requirements.

Delay Lines IC Part Context

This part belongs to the DS1100L family, which serves as the 3.3V version of the original DS1100 series. While the standard DS1100 operates at 5V, the L-series is optimized for lower voltage applications. The Z suffix indicates an SOIC package, distinguishing it from the µMAX variant found in other model numbers within the same functional family.

Delay Lines IC Replacement Considerations

Direct replacements include other DS1100LZ-xxx parts with different delay values if timing adjustments are permissible. For 5V systems, the non-L DS1100M series may be considered, though voltage level translation will be necessary.
