MICROCIRCUIT DATA SHEET Original Creation Date: 06/28/96 Last Update Date: 03/18/02 Last Major Revision Date: 03/26/97 MN54AC245-X REV 2B1 Octal Bidirectional Transceiver With TRI- State Inputs/Outputs General Description The AC245 contains eight non-inverting bidirectional buffers with 3-state outputs and is intended for bus-oriented applications. Current sinking capability is 24 mA at the A and B ports. The Transmit/Receiver (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.
