CAN transceiver for 5 V automotive and industrial buses
The 14-SOIC package houses one driver and one receiver with 50 mV of receiver hysteresis for improved noise margin on the differential bus.
It remains a current-production choice for new CAN bus nodes in automotive and industrial equipment, and no successor part has been announced that would force a redesign.
Supply rail and logic-level consideration
The CAN bus pins are 5 V tolerant. For designs using a 3.3 V microcontroller, the TCAN1043DQ1's logic input thresholds are referenced to its 5 V supply — a level-shifter or a 5 V-tolerant MCU I/O is needed on the TXD/RXD lines. The part does not include an integrated VIO pin for 3.3 V logic compatibility.
