The KK74AC623 is identical in pinout to the LS/ALS623, HC/HCT623. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs.
The KK74AC623 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.
