Octal 3-State Noninverting
Bus Transceiver
High-Performance Silicon-Gate CMOS
device inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL outputs.
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.
The IN74HC245A is identical in pinout to the LS/ALS245. The
The IN74HC245A is a 3-state noninverting transceiver that is used
Outputs Directly Interface to CMOS, NMOS, and TTL
