The 'F245 contains eight non-inverting bidirectional buffers with TRI-STATE outputs and is intended for bus-oriented applications Current sinking capability is 24 mA (20 mA Mil) at the A ports and 64 mA (48 mA Mil) at the 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 Enable input when HIGH disables both A and B ports by placing them in a High Z condition
