The
KK
74HC245A is identical in pinout to the LS/ALS245. The
device inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL outputs.
The
KK
74HC245A 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.
Outputs Directly Interface to CMOS, NMOS, and TTL
