The MAX14821 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 active-low WU output. The C/Q and DI inputs have selectable current loads for use in actuators.

An SPI™ interface allows configuration and monitoring of the device. Extensive alarm conditions are detected and communicated through the active-low IRQ output and the SPI interface. The device features reverse-polarity, short-circuit, and thermal protection. All power lines are monitored for undervoltage conditions.

The C/Q and DO drivers are specified for sourcing/sinking up to 100mA.

The device is available in a 2.5mm x 2.5mm, 25-pin WLP and a 4mm x 4mm, 24-pin TQFN package. Both are specified over the extended -40°C to +85°C temperature range.
