KK74ACT643 - Octal 3-State Bus Transceiver High-Speed Silicon-Gate CMOS
TECHNICAL DATA www.DataSheet4U.com KK74ACT643 Octal 3-State Bus Transceiver High-Speed Silicon-Gate CMOS The KK74ACT643 is identical in pinout to the LS/ALS643, HC/HCT643.
The KK74ACT623 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
The KK74ACT643 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
