The MC54/74HC245A is identical in pinout to the LS245. The device  
inputs are compatible with standard CMOS outputs; with pullup resistors,  
they are compatible with LSTTL outputs.  
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.
