TECHNICAL DATA IN74AC245 Octal 3-State Noninverting Bus Transceiver High-Speed Silicon-Gate CMOS The IN74AC245 is identical in pinout to the LS/ALS245, HC/HCT245.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs.
The IN74AC245 is a 3-state noninverting transceiver that is used for 2-way asynchronous communication between data buses.
The device has an active-low Output Enable pin, which is used to place the I/O ports int
