Octal 3-State Noninverting
Bus Transceiver
High-Speed Silicon-Gate CMOS
The IN74AC245 is identical in pinout to the LS/ALS245,
HC/HCT245. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LS/ALS
outputs.
The IN74AC245 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
