com KK74ACT623 Octal 3-State Noninverting Bus Transceiver High-Speed Silicon-Gate CMOS The KK74ACT623 is identical in pinout to the LS/ALS623, HC/HCT623.
The KK74ACT623 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
The KK74ACT623 is a 3-state noninverting transceiver that is used for 2-way communication between data buses.
Two separate enables are available.
The enable for bus A to B is active-high, the enable for bus B to A is active-low.
