DS1100LZ-20

Delay Lines IC Overview

The DS1100LZ-20 is a 3.3V, all-silicon tapped delay line featuring five equally spaced taps with a total nominal delay of 20ns. It operates within a supply voltage range of 3.0V to 3.6V and supports an industrial temperature range from -40°C to +85°C. The device utilizes an 8-pin SO package for surface-mount installation. Each tap provides precise leading- and trailing-edge accuracy and can drive up to ten 74LS loads.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays

Delay Lines IC Procurement Notes

Verify the specific suffix requirements for lead-free compliance and tape-and-reel packaging options when sourcing this component. Confirm that the selected variant matches the required operating temperature range and package dimensions for your PCB layout. Ensure compatibility with vapor-phase or IR soldering processes as specified in the datasheet.

Delay Lines IC Selection Notes

Select the DS1100LZ-20 when a fixed 20ns total delay with five intermediate taps is required at 3.3V. Consider the SO package for surface-mount assembly needs. Evaluate the tolerance specifications against application sensitivity, particularly regarding temperature and voltage variations across the industrial range.

Delay Lines IC Part Context

This component belongs to the DS1100L series, which serves as the 3.3V version of the standard DS1100 family. The series offers various delay values ranging from 4ns to 500ns, allowing designers to choose specific timing increments without programming. The DS1100LZ-20 specifically targets applications requiring lower voltage operation compared to the 5V variants.

Delay Lines IC Replacement Considerations

The DS1100LZ-20 is designed as an improved replacement for the DS1000 series. Verify pinout compatibility and electrical characteristics before substituting other delay lines.
