Octal 3-state noninverting bus transceiver with LSTTL compatibel inputs
High–Performance Silicon–Gate CMOS

The MC54/74HCT245A is identical in pinout to the LS245. This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The MC54/74HCT245A is a 3–state noninverting 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 states. The Direction control determines whether data flows from A to B or from B to A.
