Overview
74AC648 Octal Transceiver/Register with 3-STATE Outputs November 1988 Revised August 2000 74AC648 Octal Transceiver/Register with 3-STATE Outputs General Description The AC648 consists 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.
Features s Independent registers for A and B b...
