DS1004Z-4

Overview

The DS1004Z-4 is a five-tap all-silicon delay line housed in an 8-pin SOIC package. It operates on a +5V supply (4.75V to 5.25V) within a commercial temperature range of 0°C to +70°C. The device provides precise tap-to-tap nominal delays of 1.5 ns with tolerances of ±1.0 ns and ±1.75 ns over temperature and voltage variations. Input-to-Tap 1 delay is nominally 5 ns, with subsequent taps delayed by 4 ns increments up to Tap 5 at 21 ns. It features CMOS design with TTL compatibility, capable of driving up to 10 LS loads per output.

Feature Summary

• Provides five distinct delayed clock phases from a single input signal
• Maintains input symmetry through precise leading and trailing edge accuracy
• Offers CMOS logic design compatible with standard TTL interfaces

Applications

• Generating multiple delayed clock phases for synchronous digital systems
• Timing alignment and skew compensation in high-speed circuits
• Precision timing elements requiring specific tap-to-tap delay intervals

Procurement Notes

Verify the component status as discontinued or limited availability through official Analog Devices channels. Confirm that the SOIC-8 package matches the required footprint and soldering specifications. Ensure the operating temperature range meets the application requirements before finalizing procurement decisions.

Selection Notes

Select this variant when a 1.5 ns tap-to-tap delay is required. Compare against other suffixes (-2, -3, -5) if different delay increments are needed. Verify that the 8-pin SOIC package fits the board layout constraints. Check that the drive capability of 10 LS loads is sufficient for the connected circuitry.

Part Context

This component belongs to the DS1004 family of silicon delay lines manufactured by Maxim Integrated, now part of Analog Devices. The 'Z' suffix indicates the 8-pin mini-SOIC package format, distinguishing it from the DIP version. It represents a specialized timing solution designed for applications requiring precise phase shifting without external components.
