CANbus transceiver for 5V industrial networks
The Maxim Integrated MAX13051ESA+T is a full-duplex CANbus transceiver in an 8-SOIC package, handling one driver and one receiver per the 1/1 count. It operates from a 4.75V to 5.25V supply rail and supports data rates up to 1Mbps, making it a direct fit for standard CAN 2.0B and CAN FD networks running at the classic 1Mbps ceiling. The 70 mV receiver hysteresis cleans up noise on long bus runs, and the industrial temperature range of -40°C to 85°C suits factory-floor, building automation, and outdoor telecom enclosures where the bus is inside a cabinet.
Supply rail and bus timing
The 5V ±5% supply is tight enough that a clean 5V rail is required — a 3.3V system will need a level translator or a separate 5V regulator for the transceiver. At 1Mbps the propagation delay and loop timing are within the CAN bit-time budget for a 40-meter bus segment; the receiver hysteresis of 70 mV provides about 350 mV of noise margin on a 2.5V common-mode bus, which is adequate for most industrial backplanes but not for long-drop unterminated stubs.
Package and footprint
Surface-mount in an 8-SOIC narrow-body package (3.90 mm width). The footprint matches standard SOIC-8 land patterns; no thermal pad or exposed die attach, so junction temperature rise is modest at typical 5V CAN bus currents.
