Current sinking capability is 24mA at the A Ports and 64mA 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.

74F245 Octal Bidirectional Transceiver with 3-STATE Outputs

January 2008
74F245 Octal Bidirectional Transceiver with 3-STATE Outputs
• Non-inverting buffers
• Bidirectional data path
• A outputs sink 24mA
• B outputs sink 64mA

The 74F245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for busoriented applications. Current sinking capability is 24mA at the A Ports and 64mA 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.

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
