74AC646 • 74ACT646 Octal Transceiver/Register with 3-STATE Outputs
General Description
The AC/ACT646 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 data handling functions available are illustrated in Figure 1, Figure 2, Figure 3, and Figure 4.
