The IN74ACT245 is identical in pinout to the LS/ALS245,
HC/HCT245. The IN74ACT245 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS
inputs.
The IN74ACT245 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.
