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.
