Octal Bidirectional Transceiver with 3-STATE Outputs
74FR245 Octal Bidirectional Transceiver with 3-STATE Outputs August 1990 Revised August 1999 74FR245 Octal Bidirectional Transceiver with 3-STATE Outputs General Description Features The 74FR245 contains eight non-inverting bidirectional � Non-inverting buffers buffers with 3-STATE outputs and is intended for bus-ori- � Bidirectional data path ented applications. Current sinking capability is 64 mA on � A and B output sink capability of 64 mA, source both the A and B Ports. The Transmit/Receive (T/R) input capability of 15 mA determines the direction of data flow through the bidirec- � Guaranteed pin-to-pin skew tional 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.
