Analog Devices / Maxim Integrated MAX14821 IO-Link® Device Transceivers
Analog Devices MAX14821 IO-Link® Device Transceivers are 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. The onboard C/Q and DO drivers are independently configurable for push-pull, high-side (PNP), or low-side (NPN) operations. The Maxim MAX14821 detects the IO-Link C/Q wake-up condition and generates a wake-up signal on the active-low WU output. The C/Q and DI inputs have selectable current loads for use in actuators.
