Philips TJA1054A Fault-tolerant CAN Transceiver Data Sheet
The TJA1054A serves as the interface between a protocol controller and the physical bus wires in a Controller Area Network (CAN). It is primarily intended for low-speed applications up to 125 kBaud in passenger cars, providing differential receive and transmit capability. The device supports unshielded bus wires and features built-in slope control to minimize ElectroMagnetic Emission (EME).
The transceiver includes robust protection mechanisms and automatic failure management. It can automatically switch to single-wire transmission modes if a bus wire is corrupted or short-circuited, even when the CANH line is shorted to Vcc. Additionally, it supports low power modes with wake-up capabilities via the bus lines.

What causes no communication when CANH is shorted to VCC?
Only the TJA1054 tolerates a CANH‑to‑VCC short circuit; the PCA82C252 and TJA1053 do not support this condition.
From: Philips PCA82C252 / TJA1053 / TJA1054 / TJA1054A Application Note
How can I reduce current consumption in low‑power modes?
The TJA1054 operates down to 5 V and its low‑power current is about 30 µA, compared with 70 µA for the TJA1053, providing lower standby consumption.
