74ABT245 Octal Bi-Directional Transceiver with 3-STATE Outputs September 1991 Revised November 1999 74ABT245 Octal Bi-Directional Transceiver with 3-STATE Outputs General Description The ABT245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus-oriented applications. Current sinking capability is 64 mA on both the A and 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.
