DS1100Z-35/T&R

Delay Lines IC Overview

The DS1100Z-35/T&R is a five-tap silicon delay line from the DS1100 series, manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced delays with a nominal tap-to-tap interval of 7ns and a total delay of 35ns across five taps. The device operates on a single +5V supply (4.75V to 5.25V) and features low-power CMOS technology compatible with TTL/CMOS logic levels. Packaged in an 8-pin SOIC surface-mount format, it is supplied in tape and reel configuration for automated assembly. The component supports an operating temperature range of -40°C to +85°C.

Delay Lines IC Feature Summary

• Five equally spaced output taps provide precise timing intervals derived from a single input signal.
• Reproduces both leading and trailing edges with high accuracy using all-silicon circuitry.
• Each tap output can drive up to ten 74LS loads, ensuring robust signal distribution.

Delay Lines IC Applications

• Timing element generation for digital logic circuits
• Pulse width modulation and duty cycle control
• Clock skew compensation in data transmission systems

Delay Lines IC Procurement Notes

Verify the specific ordering suffix to confirm the package type and delivery method. The T&R suffix indicates a tape and reel packaging format suitable for automated pick-and-place manufacturing processes. Ensure compatibility with standard SOIC footprint land patterns during PCB layout design.

Delay Lines IC Selection Notes

Select this part when a fixed 35ns total delay with five intermediate steps is required. Verify that the system operates within the specified 4.75V to 5.25V voltage range. Consider the -35 designation for the specific delay value and ensure the SOIC package fits the available board space constraints.

Delay Lines IC Part Context

This component belongs to the DS1100 family of economy timing elements. The Z suffix denotes the 8-pin SOIC package variant, while the numeric suffix specifies the delay characteristics. It serves as a direct replacement for older hybrid technologies like the DS1000, offering improved reliability and lower cost through monolithic silicon integration.

Delay Lines IC Replacement Considerations

The datasheet identifies the DS1100 as an improved replacement for the DS1000 series. Designers transitioning from legacy parts should verify pinout compatibility and electrical parameter alignment before substitution.

Delay Lines IC FAQ

How are the delay values distributed across the taps?

The delays are equally spaced. For the DS1100Z-35, each tap adds a nominal 7ns increment, resulting in tap delays of 7ns, 14ns, 21ns, 28ns, and 35ns respectively.

What is the maximum input pulse frequency?

The device supports input frequencies up to 1MHz. Higher frequencies may result in increased active current consumption and potential variations in delay accuracy depending on application conditions.

Is the delay tolerance affected by temperature changes?

Yes. The delay tolerance varies with temperature. For delays greater than 40ns, the tolerance is ±5% at +25°C, expanding to ±13% over the full industrial temperature range of -40°C to +85°C.
