DS1100LZ-45/T&R

Delay Lines IC Overview

The DS1100LZ-45/T&R is a 3.3V five-tap silicon delay line from the DS1100L series, designed for surface-mount applications to conserve PCB area. It provides equally spaced taps with nominal delays of 9ns, 18ns, 27ns, 36ns, and 45ns at Taps 1 through 5, respectively. 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 SO format, it features low-power CMOS technology compatible with TTL and CMOS logic levels.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays over commercial and industrial temperature ranges
• Five equally spaced taps capable of driving up to ten 74LS loads each
• Designed to reproduce both leading and trailing edges with equal precision
• Low-power CMOS construction ensuring superior reliability compared to hybrid technology

Delay Lines IC Applications

• Timing element replacement for legacy DS1000 devices
• Fast-turn prototyping requiring custom or standard delay values
• Digital signal processing circuits requiring fixed pulse width extension

Delay Lines IC Procurement Notes

Verify that the specific suffix /T&R corresponds to tape-and-reel packaging rather than tube packaging when sourcing components. Confirm RoHS compliance status by checking for the lead-free designation in the ordering information table. Ensure the selected variant matches the required operating temperature range and package dimensions for the target PCB layout.

Delay Lines IC Selection Notes

Select this component when a 3.3V supply is available and surface-mount integration is preferred over DIP packages. Choose the -45 suffix specifically when tap delays of 9ns through 45ns are required. Consider the DS1100U series if a 5V supply voltage is necessary instead of the 3.3V requirement of the DS1100L series.

Delay Lines IC Part Context

This part belongs to the DS1100L family, which represents the 3.3V version of the broader DS1100 series. While the standard DS1100 operates at 5V, the DS1100L variants are optimized for lower voltage applications. The LZ suffix indicates an 8-pin SO package, distinguishing it from the LU suffix used for µMAX packages within the same electrical family.

Delay Lines IC FAQ

What is the maximum input pulse width supported by the DS1100LZ-45?

The datasheet specifies a typical input pulse width of 500ns, though wider pulses such as 1µs are noted for the -500 version.

How does the delay tolerance vary across different temperatures?

For delays greater than 40ns, the tolerance ranges from ±5% at +25°C to ±13% at -40°C to +85°C.

Can individual taps be disabled or programmed?

No, the DS1100L is an unprogrammable delay line where all five taps provide fixed, equally spaced delays relative to the input.
