The Transmit/ Receive T/R input determines the direction of data flow through the bidirectional transceiver. Transmit activeHIGH enables data from A Ports to B Ports Receive active-LOW enables data from B Ports to A Ports. The Output Enable input, when HIGH, disables both A and B Ports by placing them in a high impedance state. The equivalent resistor in the B Port helps reduce output overshoot and undershoot.
