Analog Devices / Maxim Integrated MAX14824 IO-Link® Master Transceiver

Analog Devices MAX14824 IO-Link® Master Transceiver is an IO-Link master interface that integrates an IO-Link physical layer transceiver with an auxiliary digital input and two linear regulators. High port count IO-Link master applications are supported through in-band SPI addressing. The 12MHz SPI interface minimizes host controller access times. In-band addressing and selectable SPI addresses enable cascading up to 16 devices. 

The Analog Devices MAX14824 IO-Link® Master Transceiver supports all the IO-Link data rates and features slew-rate-controlled drivers to reduce EMI. The driver is guaranteed to drive up to 300mA (min.) load currents. Internal wake-up circuitry automatically determines the correct wake-up polarity, allowing for the use of simple UARTs for wake-up pulse generation. The ADI MAX14824 operates over the extended -40°C to +105°C temperature range.
