Features, Applications
54F 74F245 Octal Bidirectional Transceiver with TRI-STATE Outputs

The 'F245 contains eight non-inverting bidirectional buffers with TRI-STATE outputs and is intended for bus-oriented applications Current sinking capability (20 mA Mil) at the A ports and (48 mA Mil) 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


Non-inverting buffers Bidirectional data path A outputs sink (20 mA Mil) B outputs sink (48 mA Mil) Guaranteed 4000V minimum ESD protection
