Description

The 74ACQ646SC 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 Figure 4.

The 74ACQ646SC utilizes Fairchild Quiet Series^TM technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series^TM features GTO^TM output control and undershoot corrector in addition to a split ground bus for superior performance.
