General description

The TJA1054A is the interface between the protocol controller and the physical bus wires

in a Controller Area Network (CAN). It is primarily intended for low-speed applications up

to 125 kBd in passenger cars. The device provides differential receive and transmit

capability but will switch to single-wire transmitter and/or receiver in error conditions.

The TJA1054A is the ElectroStatic Discharge (ESD) improved version of the TJA1054.

The TJA1054AT is, as the TJA1054T, pin and downwards compatible with the

PCA82C252T and the TJA1053T. This means that these two devices can be replaced by

the TJA1054AT or the TJA1054T with retention of all functions.

The most important improvements of the TJA1054 and the TJA1054A with respect to the

PCA82C252 and the TJA1053 are:

and CANH output signals
