Philips TJA1054 Fault-tolerant CAN Transceiver Data Sheet
The Philips TJA1054 is a fault-tolerant CAN transceiver designed as an interface between a protocol controller and physical bus lines. It is primarily intended for low-speed applications, specifically up to 125 kBaud, in passenger cars.
Key features include support for unshielded bus wires due to built-in slope control functions and very good matching of the CANL and CANH outputs. The device offers automatic switching to single-wire transmission modes in the event of bus failures, such as short-circuits or interruptions, ensuring continued operation even when the CANH bus wire is short-circuited to Vcc.

Questions answered in these manuals
What is the maximum baud rate for the TJA1054?
The device supports a baud rate up to 125 kBaud.
From: Philips TJA1054 Fault-tolerant CAN Transceiver Data Sheet
Does the TJA1054 support unshielded bus wires?
Yes, it supports unshielded bus wires due to built-in slope control functions.

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.
