Pixhawk 4 Telemetry port 5V tolerant

Hello, I have a telemetry radio that generates 5V for RTS CTS RX and TX and I would like to know if the pins of TELEM1 and TELEM2 support 5V, the information I found about it generates some doubts.

Has anyone found themselves in the same situation?

Hi, in autopilots from CUAV it’s connected to 5V tolerant pins.
