The PI74LCX245 is an 8-bit bidirectional transceiver designed for asynchronous two-way communication between data buses. The transmit/receive input pin (T/R) determines the direction of data flow through the bidirectional transceiver. Transmit (active HIGH) enables data from A ports to B ports, and receive (active LOW) from B ports to A ports. The output enable (OE) input, when HIGH, disables both A and B ports by placing them in HIGH Z condition. The PI74LCX245 can be driven from either 3.3V or 5.0V devices allowing this device to be used as a translator in a mixed 3.3V/5.0V system. Logic Block Diagram
