Octal Transceiver/Register
with 3ĆState Outputs (Inverting)
The MC74AC648/74ACT648 consist of registered bus transceiver circuits,
with outputs, D-type flip-flops and control circuitry providing multiplexed transmission
of data directly from the input bus or from the internal storage registers. Data on the
A or B bus will be loaded into the respective registers on the LOW-to-HIGH transition
of the appropriate clock pin (CAB or CBA). The four fundamental data handling
functions available are illustrated in the following figures.

* The data output functions may be enabled or disabled by various signals at the G and DIR 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 appropriate clock inputs.
