Hi, everybody!

Thanks all! |

| Transmit A and Transmit B. The signal is effectively push-pull and the A output is the non-inverting output. The Receive A pin is the one which in a failsafe device will be held mark high, signal idle state, if all transmitters on the bus are in their high impedance state. |
