Hi all,
in our design, both inputs /RE & DE are connected together, so that the device switches from receiver-enable directly to transmitter-enable – without a both-disabled state in-between.
Could you please tell us the required enable times for this case?
And what is the necessary minimum disable time, which leads to the long enabling time for the transmitter and receiver?
Currently, we just wait about 40 ns instead of 3…8 μs, and it works fine – but we aren’t sure if this is enough for ensuring stable operation under all circumstances.
Best regards,
Frank Brütting
