BUS MANAGEMENT FUNCTIONS
The following examples demonstrate the four fundamental
bus-management functions that can be performed with the
74ALS651/74ALS651-1 and 74ALS652/74ALS652-1. The select
pins determine whether data is stored or transferred through the
device in real time. The output enable pins determine the direction of
the data flow.
