MC74ACT646DWR2G

Bus XCVR Single 8CH 3-ST 24Pin SOIC T/R

The MC74AC646/74ACT646 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 CAB or CBA. The four fundamental data handling functions available are illustrated in the following figures.
