Product details

Galvanically isolated CAN transceiver for automotive and industrial buses

The NXP TJA1052IT/5Y is a galvanically isolated CAN transceiver that integrates capacitive coupling to provide 5000Vrms isolation between the CAN bus and the controller side. It supports data rates up to 5Mbps, making it suitable for CAN FD networks that need higher throughput than classic 1Mbps CAN. The part is AEC-Q100 qualified and rated for -40°C to 125°C, covering under-hood automotive and industrial environments where wide temperature swings are the norm. A single unidirectional channel with 1/1 input/output configuration keeps the signal path clean for standard CAN or CAN FD frames.

Supply range and 3.3V compatibility

The supply range spans 3V to 5.25V, so the part works directly on a 3.3V CAN bus without a level shifter. Many modern MCUs run their CAN controller at 3.3V, and this isolator matches that rail on both sides.

Frequently asked questions

Is TJA1052IT/5Y compatible with 3.3V CAN bus?

Yes. The supply range is 3V to 5.25V, so the part operates directly on a 3.3V CAN bus without additional level translation.

Can TJA1052IT/5Y be used for CAN FD?

Yes. The data rate is rated at 5Mbps, which exceeds the 1Mbps limit of classic CAN and supports CAN FD frames.

What is the pinout of TJA1052IT/5Y?

The TJA1052IT/5Y is supplied in a 16-SOIC package (7.50mm width, supplier device package 16-SO). The pinout follows the standard isolated CAN transceiver layout for this footprint. Refer to the NXP datasheet for the full pin assignment.
