The MAX306CWI from Analog Devices is a low-power analog isolator for transmit and receive (T/R) signal isolation applications. This IC transmits and receives data over a single pair of conductors, with a maximum data rate of 4 Mbps. It operates from a single +5V supply, with a temperature range of -40°C to +85°C. The MAX306CWI supports a wide range of applications, such as controlling remote relays, motors, and sensors, providing a galvanic isolation barrier between the input/output ports and the host or controller. It features a wide common-mode voltage range of 0V to 8V and a maximum peak-to-peak data voltage of 18V. Additionally, it has an integrated watchdog timer, which monitors the operational state of the IC and resets it if an error occurs.
