MAX14826
IO-Link Device Transceiver
General Description
The MAX14826 transceiver is suitable for IO-Link®
devices and 24V binary sensors. 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/THSD output.
The MAX14826 includes a selectable parallel or SPI
interface for configuration and monitoring of the drivers.
Extensive alarm conditions are detected and communicated
through the interrupt outputs 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 sinking/sourcing
200mA.
The MAX14826 is available in a 4mm x 4mm, 24-pin
TQFN package, and is specified over the extended -40°C
to +105°C temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
Package Thermal Characteristics (Note 1)

Junction-to-Case Thermal Resistance (θJC)..................3°C/W
Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
