1 / 10 page © Semiconductor Components Industries, LLC, 2015 March, 2015 − Rev. 7 1 Publication Order Number: MC74AC646/D MC74AC646, MC74ACT646 Octal Transceiver/Register with 3-State Outputs (Non-inverting) 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 Figures 1 to 4. Features • Independent Registers for A and B Buses • Multiplexed Real−Time and Stored Data Transfers • Choice of True and Inverting Data Paths • 3−State Outputs • 300 mil Slim Dual In−Line Package • Outputs Source/Sink 24 mA • ′ACT646 Has TTL Compatible Inputs • These are Pb−Free Devices REAL TIME TRANSFER A‐BUS TO B‐BUS REAL TIME TRANSFER B‐BUS TO A‐BUS REG REG REG REG REG REG REG REG B‐BUS B‐BUS A‐BUS A‐BUS B‐BUS B‐BUS A‐BUS A‐BUS STORAGE FROM BUS TO REGISTER TRANSFER FROM REGISTER TO BUS Figure 1.
