The DS2406P+ is a dual addressable switch plus 1Kb memory in 6 pin TSOC package. This dual addressable switch plus memory offers a simple way to remotely control a pair of open drain transistors and to monitor logic level at each transistor's output via the 1-wire bus for closed loop control. It has its own 64bit ROM registration number that is factory lasered into chip to provide a unique identity for absolute traceability. The device's 1024bits of EPROM can be used as electronic label to store information such as switch function, physical location and installation date. Communication with DS2406 follows standard Dallas semiconductor 1-wire protocol and can be accomplished with minimal hardware such as a single port pin of a microcontroller. It is used in process control, HVAC systems, IEEE 1451.4 sensor TEDS, system configuration & monitoring.
