DS1004Z-4/T&R

Overview

The DS1004Z-4/T&R is a five-tap all-silicon delay line manufactured by Analog Devices Inc. (formerly Maxim Integrated) in an 8-pin SOIC package. It operates on a single +5V supply with a voltage range of 4.75V to 5.25V and functions within a 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 at room temperature and ±1.75 ns over temperature and voltage variations. Input-to-Tap 1 delay is nominally 5 ns. Each output can drive up to 10 LS loads, featuring CMOS design with TTL compatibility.

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

• Precision timing circuits requiring multiple phase-shifted signals
• High-speed digital systems utilizing silicon-based delay elements
• Clock distribution networks needing specific tap-to-tap delay intervals

Procurement Notes

Verify the component status as discontinued or obsolete before initiating procurement. Confirm that the tape and reel packaging suffix matches the required manufacturing process for surface mount assembly. Ensure the ordering suffix corresponds exactly to the specified delay tolerance variant to avoid functional mismatches in timing-critical designs.

Selection Notes

Select this component when a fixed five-tap delay structure is required without programmable adjustment. Compare the ±1.0 ns tap-to-tap tolerance against system jitter requirements. Verify that the 8-pin SOIC footprint aligns with the existing PCB layout constraints and thermal management specifications for the target application environment.

Part Context

This part belongs to the DS1004 family of high-speed silicon delay lines. Variants such as DS1004Z-2, DS1004Z-3, and DS1004Z-5 offer different nominal tap-to-tap delays ranging from 1.5 ns to 5 ns while maintaining the same physical package and electrical interface characteristics.

Replacement Considerations

Direct replacements include other DS1004Z variants with matching pinouts but different delay values. Cross-reference with DS1004M series for DIP package equivalents if form factor changes are permissible.
