General Description
The ACQ/ACTQ646 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 (CPAB or CPBA).
The four fundamental handling functions available are illustrated in Figure 1, Figure 2, Figure 3 and F...
