MC74HC245A  
Octal 3-State Noninverting  
Bus Transceiver  
High−Performance Silicon−Gate CMOS  
The MC74HC245A is identical in pinout to the LS245. The device  
inputs are compatible with standard CMOS outputs; with pull−up  
resistors, they are compatible with LSTTL outputs.  
http://onsemi.com  
The HC245A 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.
