Octal 3-State Noninverting Bus Transceiver
High-Speed Silicon-Gate CMOS

The IN74ACT623 is identical in pinout to the LS/ALS623, HC/HCT623. The IN74ACT623 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
The IN74ACT623 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.
