BUS MANAGEMENT FUNCTIONS
The following examples demonstrate the four fundamental
bus-management functions that can be performed with the
74ALS646/646-1 and 74ALS648/648-1.
The select pins determine whether data is stored or transferred
through the device in real time.
The DIR determines which bus will receive data when the OE pin is
Low.
