The following examples demonstrate the four fundamental
bus-management functions that can be performed with the 74F651A
and 74F652A. 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.

1. H =
High-voltage level
2. L

Low-voltage level
3. *
=
The data output function may be enabled or disabled by various signals at the OEBA and OEAB inputs. Data input functions are
always enabled, i.e., data at the bus pins will be stored on every low-to-high transition of the clock.
