TJA144x Automotive CAN FD Transceiver Family

画像にカーソルを合わせると拡大表示されます。

The TJA144x family of transceivers provides an interface between a controller area network (CAN) or CAN flexible data rate (FD) protocol controller and the physical two-wire CAN-bus.

TJA1441: Basic CAN
TJA1442: Standby mode CAN
TJA1443: Sleep mode CAN
TJA1448: Dual channel standby mode CAN

All variants enable reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s.

The TJA144x is intended as a simple replacement for high-speed classical CAN and CAN FD transceivers. It offers pin compatibility and is designed to avoid changes to hardware and software design, allowing the TJA1442 to be easily retrofitted to existing applications.

AEC-Q100 Grade 0 variants, the TJR144x, are available for high temperature applications, supporting operation at 150°C ambient temperature.

A variant optimized for use in very low-speed industrial solutions is available, the TJF1441.
