Octal Transceiver/Register With
3ĆState Outputs (NonĆInverting)
The MC74AC/ACT652 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 (CAB or CBA). The four fundamental data handling
functions available are illustrated in Figures 1 to 4.
Independent Registers for A and B Buses
Multiplexed Real-Time and Stored Data Transfers
