EVALUATION KIT AVAILABLE MAX14820 IO-Link Device Transceiver General Description The MAX14820 transceiver is suitable for IO-Link® devices and 24V binary sensors/actuators. All specified IO-Link data rates are supported. In IO-Link applications, the transceiver acts as the physical layer interface to a microcontroller running the data-link layer protocol. Additional 24V digital inputs and outputs are provided. Two internal linear regulators generate common sensor and actuator power requirements: 5V and 3.3V. On-board C/Q and DO drivers are independently configurable for push-pull, high-side (PNP), or low-side (NPN) operation. The device detects the IO-Link C/Q wake-up condition and generates a wake-up signal on the activelow WU output.
