IN74ACT643 Octal Bus Transceiver

TECHNICAL DATA IN74ACT643 Octal 3-State Bus Transceiver High-Speed Silicon-Gate CMOS The IN74ACT643 is identical in pinout to the LS/ALS643, HC/HCT643. The IN74ACT623 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The IN74ACT643 is a 3-state 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 into high-impedance states. The Directio.
