DS2401-SL+T&R

Specialized ICS Overview

The DS2401-SL+T&R is a silicon serial number IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a guaranteed unique 64-bit ROM ID for absolute traceability, comprising an 8-bit family code (01h), a 48-bit serial number, and an 8-bit CRC tester. The device utilizes a minimalist 1-Wire interface requiring only a single data lead and ground return, with power derived from the data line itself. It operates within a voltage range of 2.8V to 6.0V and supports an industrial temperature range of -40°C to +85°C. The component is housed in a TO-92 package with straight leads.

Specialized ICS Feature Summary

• Guaranteed Unique 64-Bit ROM ID: Includes 8-bit Family Code, 48-bit Serial Number, and 8-bit CRC.
• Minimalist 1-Wire Interface: Reduces control, address, data, and power requirements to a single pin.
• Bus-Powered Operation: Zero standby power required; power derived directly from the data line.
• Straight Lead Configuration: TO-92 package variant with straight leads (SL) designed for tape-and-reel processing.

Specialized ICS Applications

• PCB Identification
• Network Node ID
• Equipment Registration

Specialized ICS Procurement Notes

Verify that the specific ordering suffix 'SL' corresponds to the straight lead configuration as defined in the manufacturer's documentation. Confirm the presence of the '+' designation indicates lead-free/RoHS-compliant packaging. Ensure the 'T&R' suffix matches the required tape-and-reel quantity for automated assembly processes.

Specialized ICS Selection Notes

Select this part when a unique hardware identifier is required for devices on a 1-Wire network. The DS2401-SL+T&R is specifically suited for applications necessitating through-hole mounting with straight leads compatible with standard reflow or wave soldering equipment utilizing tape-and-reel dispensers.

Specialized ICS Part Context

The DS2401 serves as an electronic registration number providing a unique identity determined via a minimal electronic interface. It functions as a peripheral on the 1-Wire bus system, allowing multiple devices to reside on a common net. This specific model represents the tape-and-reel version of the TO-92 package with straight leads.

Specialized ICS Replacement Considerations

The DS2401A+T&R is a related variant within the same series offering similar functionality but with different electrical characteristics regarding pullup resistance ranges. Verify compatibility with existing bus controller circuitry if substituting between these variants.
