It provides bidirectional drive for bus-oriented microprocessor and digital communications systems. Straight through bidirectional transceivers are featured, with 24 mA bus drive capability on the A Ports and 64 mA bus drive capability on the B Ports. One input, Transmit/Receive (T/R) determines the direction of logic signals through the bidirectional transceiver. Transmit enables data from A-to-B Ports; Receive enables data from B-to-A Ports. The Output Enable input disables both A and B Ports by placing them in a 3-STATE condition.
