74F245 Octal Bidirectional Transceiver with 3-STATE Outputs April 1988 Revised April 1999 74F245 Octal Bidirectional Transceiver with 3-STATE Outputs General Description The 74F245 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 Ports and 64 mA at the 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.
