1 / 8 page 5-1 FACT DATA Octal Transceiver/Register With 3State Outputs (NonInverting) 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 • Choice of True and Inverting Data Paths • 3-State Outputs • 300 mil Slim Dual-in-Line Package • Outputs Source/Sink 24 mA • ′ACT652 Has TTL Compatible Inputs TRANSFER FROM REGISTER TO BUS REG REG A-BUS B-BUS REAL TIME TRANSFER A-BUS TO B-BUS REG REG A-BUS B-BUS REAL TIME TRANSFER B-BUS TO A-BUS REG REG A-BUS B-BUS Figure 1 Figure 2 STORAGE FROM BUS TO REGISTER REG REG A-BUS B-BUS Figure 3 Figure 4 MAXIMUM RATINGS* Symbol Parameter Value Unit VCC DC Supply Voltage (Referenced to GND) –0.5 to +7.0 V Vin DC Input Voltage (Referenced to GND) –0.5 to VCC + 0.5 V Vout DC Output Voltage (Referenced to GND) –0.5 to VCC + 0.5 V Iin DC Input Current, per Pin ± 20 mA Iout DC Output Sink/Source Current, per Pin ± 50 mA ICC DC VCC or GND Current per Output Pin ± 50 mA Tstg Storage Temperature –65 to +150 °C * Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the Recommended Operating Conditions.
