KK74ACT640 Description
Octal 3-State Inverting Bus Transceiver High-Speed Silicon-Gate CMOS The KK74ACT640 is identical in pinout to the LS/ALS640, HC/HCT640. The KK74ACT640 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The KK74ACT640 is a 3-state transceiver that is used for 2-way asynchronous munication between data buses.
