DS1100Z-150/T&R

Delay Lines IC Overview

The DS1100Z-150/T&R is a five-tap silicon delay line from the DS1100 series, manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced timing taps with a nominal total delay of 150ns, distributed as 30ns, 60ns, 90ns, 120ns, and 150ns per tap. The device operates on a single 5V supply (4.75V to 5.25V) within an industrial temperature range of -40°C to +85°C. Packaged in an 8-pin SOIC surface-mount format, it features low-power CMOS technology compatible with TTL/CMOS logic levels. Each tap can drive up to 10 LS loads, ensuring robust signal reproduction for both leading and trailing edges.

Delay Lines IC Feature Summary

• Five equally spaced output taps provide precise timing delays across the signal path.
• Low-power CMOS construction ensures compatibility with standard TTL and CMOS logic families.
• All-silicon design offers superior reliability compared to hybrid technologies while saving PCB area.

Delay Lines IC Applications

• Precision timing circuits requiring fixed delay intervals
• Signal synchronization and pulse stretching applications
• Replacement for legacy DS1000 delay line components

Delay Lines IC Procurement Notes

Verify that the specific suffix /T&R indicates tape-and-reel packaging rather than tube packaging when sourcing this component. Confirm the lead-free (+) status if RoHS compliance is required for the assembly process. Ensure the ordering part number matches the exact 150ns delay specification to avoid functional mismatches in timing-critical designs.

Delay Lines IC Selection Notes

Select this model when a fixed 150ns total delay with five intermediate taps is required. Consider the 8-pin SO package dimensions for board space constraints. Verify that the input pulse width meets the minimum requirements specified in the AC electrical characteristics to maintain delay accuracy at high frequencies.

Delay Lines IC Part Context

This component belongs to the DS1100 family of economy timing elements. The 'Z' suffix denotes the 8-pin SO package variant, while the '/T&R' suffix specifies tape-and-reel shipping. It serves as a direct replacement for older DS1000 series devices, offering improved performance in a smaller surface-mount footprint.

Delay Lines IC Replacement Considerations

DS1100Z-150+ and DS1100Z-150 are functionally equivalent alternatives differing primarily in packaging quantity or RoHS status.

Delay Lines IC FAQ

How does the delay tolerance vary with temperature?

For delays greater than 40ns, such as the 150ns total delay of this part, the tolerance ranges from -5% to +5% at +25°C, expanding to -13% to +13% over the full -40°C to +85°C operating range.

What is the maximum input frequency for accurate operation?

The datasheet specifies a minimum input pulse width of 20% of Tap 5 delay. For the DS1100Z-150, this implies a period constraint, though higher frequencies may result in variable delay accuracy depending on decoupling and layout.
