DS2406P

Specialized Overview

The DS2406P is a dual addressable switch with integrated 1Kb memory, manufactured by Analog Devices Inc./Maxim Integrated. It operates on the 1-Wire bus protocol and communicates at speeds up to 15.4 kbits/s. The device functions within a voltage range of 2.8V to 6.0V and supports an operating temperature range from -40°C to +85°C. PIO channel A provides a sink capability of 50mA at 0.4V with soft turn-on, while channel B offers 8mA at 0.4V. Maximum operating voltages are 13V for PIO-A and 6.5V for PIO-B. The component includes a unique factory-lasered 64-bit registration number and utilizes a 6-pin TSOC package.

Specialized Feature Summary

• Provides closed-loop control via open drain PIO pins monitored over the 1-Wire bus
• Contains 1024 bits of user-programmable OTP EPROM for electronic labeling
• Features a unique 64-bit factory-lasered registration number for absolute identity
• Supports conditional search commands based on user-specified conditions

Specialized Applications

• HVAC systems
• IEEE 1451.4 sensor TEDS applications
• Process control
• System configuration and monitoring

Specialized Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel configuration. The 'P' designation indicates the 6-pin TSOC package. Confirm lead-free compliance status if required by assembly specifications. Ensure the supplier source matches the manufacturer's authorized distribution channels to guarantee authenticity and traceability of the laser-etched ROM codes.

Specialized Selection Notes

Select this component when independent control of two open-drain outputs is required alongside non-volatile data storage. It serves as a direct replacement for the DS2407, though it lacks hidden mode and user-programmable power-on settings. Consider the TSOC package availability and the requirement for parasite or external VCC power supply options during system design.

Specialized Part Context

This component belongs to the Dallas Semiconductor 1-Wire family of devices. It shares the same family code (12h) with the DS2407 but is distinguished by its status memory layout. The device integrates a multidrop controller to ensure compatibility with other 1-Wire network products, allowing multiple units to operate independently on a single bus line.

Specialized Replacement Considerations

The DS2406P is fully compatible with and replaces the DS2407. Designers must account for the absence of Hidden Mode and user-programmable power-on settings in the DS2406 compared to the DS2407.
