Maxim's IO-Link is a 3-wire industrial communications standard designed for linking sensors and actuators into control networks. In IO-Link applications, the transceiver acts as the physical layer interface to a microcontroller running the data-link layer protocol while supporting up to 24 V digital inputs and outputs. Maxim transceivers support all IO-Link specifications.

The MAX14819 low-power, dual-channel, IO-Link master transceiver with sensor/actuator power-supply controllers is fully compliant with the latest IO-Link and binary input standards and test specifications, IEC 61131-2, IEC 61131-9 SDCI, and IO-Link 1.1.2. This master transceiver also includes two auxiliary digital input (DI_) channels.

The MAX14827 dual-channel, 250 mA transceiver integrates high-voltage functions commonly found in industrial sensors, including drivers and regulators. It features two ultra-low-power drivers with active reverse-polarity protection to reduce downtime. Operation is specified for normal 24 V supply voltages up to 60 V. Transient protection is simplified due to high-voltage tolerance allowing the use of micro TVS.
