IO-Link physical-layer transceiver for 24V industrial buses
The MAX14826GTG+ from Maxim Integrated is a single-channel IO-Link transceiver in a 24-TQFN (4x4) package with an exposed pad for thermal management. It integrates one driver and one receiver (1/1) and operates over a 9V to 36V supply range, covering the standard 24V industrial rail with margin for transients. The -40°C to 105°C temperature grade suits factory-floor sensor/actuator cabinets, outdoor telecom enclosures, and under-hood automotive IO-Link master ports. The exposed pad requires a thermal-via pattern under the package to pull heat into the PCB ground plane — verify your layout has that clearance before committing the BOM.
Supply range and temperature — what they mean for the BOM
The 9V to 36V supply range means this transceiver can run directly from a 24V industrial PSU without a pre-regulator, as long as the PSU holds within that window under load and ripple. The -40°C to 105°C operating range covers extended industrial and automotive cabin applications; no derating is needed for ambient temperatures up to 105°C, but self-heating from the driver output should be checked against the package thermal resistance. The 1/1 driver/receiver count confirms this is a single-port transceiver — one IO-Link channel per package, so a four-port master needs four of these.
