The is an octal Bidirectional Transceiver with 3-state inputs/outputs and is intended for bus-oriented applications. Current sinking capability is 24mA at both the A and B ports. The transmit/receive T/R input determines the direction of data flow through the bidirectional transceiver. Transmit active-HIGH enables data from A ports to B ports, receive active-LOW enables data from B ports to A ports. The output enables input, when HIGH disables both A and B ports by placing it in a HIGH Z condition.
