74LVX245
Low Voltage Octal Bidirectional Transceiver
General Description
The LVX245 contains eight non-inverting bidirectional buff-
ers is intended for bus-oriented applications. 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 (ac-
tive-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.
