Below 4.5 V the transceiver may not drive the recessive/dominant levels correctly, so a separate 5 V LDO for the CAN transceiver is common in mixed-voltage designs. That covers cold-crank at -40°C and the junction temperature inside a sealed ECU near the engine. For industrial applications, the same range handles outdoor enclosures in direct sun or near a motor drive. The 8-SOIC package with 3.90 mm width fits standard footprints, and the surface-mount assembly is straightforward for reflow. The base product number TCAN1042 covers multiple variants (different temperature grades and wake features), but the HGD suffix specifically denotes the 8-SOIC package and the extended temperature range.","metaTitle":"TCAN1042HGD CAN Transceiver, 5 Mbps, 8-SOIC, -55 to 125°C","metaDescription":"TCAN1042HGD CAN transceiver from TI. 5 Mbps data rate, 4.5V-5.5V supply, -55°C to 125°C range.
