Overview
com 54AC646 Octal Transceiver/Register with TRI-STATE Outputs August 1998 54AC646 Octal Transceiver/Register with TRI-STATE ® Outputs General Description The ’AC646 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 Figures 1, 2, 3, 4.
