Overview
The TJA1054T/N,118 is a fault-tolerant CAN (Controller Area Network) transceiver produced by NXP USA Inc. This device serves as the interface between the CAN protocol controller and the physical bus wires, primarily intended for low-speed applications up to 125 kBd, particularly in passenger cars. It offers differential receive and transmit capabilities and can switch to single-wire transmitter and/or receiver in error conditions, ensuring robust communication even in fault scenarios.

- Very low Electromagnetic Emission (EME) due to good matching of the CANL and CANH output signals.
- Good Electromagnetic Interference (EMI) performance, especially in low power modes.
- Full wake-up capability during bus failures.
- Extended bus failure management, including short-circuit of the CANH bus line to VCC.
- Support for easy system fault diagnosis.
- Two-edge sensitive wake-up input signal via the WAKE pin.
Applications
The TJA1054T/N,118 is primarily used in automotive applications, particularly in passenger cars, for low-speed CAN communication up to 125 kBd. It is suitable for various in-vehicle network systems where robust and fault-tolerant communication is essential.
