The
KK
74ACT245 is identical in pinout to the LS/ALS245,
HC/HCT245. The
KK
74ACT245 may be used as a level converter for
interfacing TTL or NMOS outputs to High Speed CMOS inputs.
The
KK
74ACT245 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.
