The TJA144x family of CAN transceivers provides the interface between a CAN or CAN FD protocol controller and a two-wire CAN bus. The family includes the TJA1441, TJA1442, TJA1443, and dual-channel TJA1448, supporting CAN FD communication at data rates up to 5 Mbit/s. Designed as a drop-in replacement for high-speed CAN and CAN FD transceivers, the TJA144x family enables hardware and software compatibility with existing designs. Grade 0 TJR144x variants support operation up to 150 °C ambient temperature, while the TJF1441 variant is optimized for very low-speed industrial applications.
