DS2401Z

Specialized ICS Overview

The DS2401Z+ is a silicon serial number integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides a guaranteed unique 64-bit registration number consisting of an 8-bit family code, a 48-bit serial number, and an 8-bit CRC tester. The device utilizes a minimalist 1-Wire interface that reduces control, address, data, and power to a single pin, communicating at speeds up to 16.3kbps. Operating within an extended voltage range of 2.8V to 6.0V and an industrial temperature range of -40°C to +85°C, it requires zero standby power as energy is derived from the data line itself.

• Extended Voltage Range: 2.8V to 6.0V
• Industrial Temperature Range: -40°C to +85°C

Specialized ICS Applications

• PCB Identification
• Network Node ID
• Equipment Registration

Specialized ICS Procurement Notes

Verify the specific package variant (SOT-223) and lead-free status (+ suffix) against project requirements. Confirm pullup resistor values align with the DS2401 specifications (1.5kΩ to 5kΩ). Ensure the bus controller supports the required 1-Wire protocol timing for reliable initialization and data retrieval.

Specialized ICS Selection Notes

Select the DS2401Z+ when surface-mount SOT-223 packaging is preferred over through-hole options. This model supports standard assembly equipment handling. Verify compatibility with existing 1-Wire controllers, noting that while compatible with DS2400, it offers enhanced multi-drop capabilities on a common net.

Specialized ICS Part Context

The DS2401Z+ belongs to the DS2401 series of silicon serial numbers. It serves as an upgrade to the DS2400, offering full reverse-compatibility while adding robust multidrop functionality. The 'Z' designation specifically indicates the SOT-223 surface-mount package configuration.

Specialized ICS Replacement Considerations

The DS2401A+ is a compatible alternative within the same family. Note that the DS2401A+ has different electrical characteristics, including a lower maximum pullup voltage (5.25V) and tighter pullup resistance requirements (300Ω to 2.2kΩ).
