MC74AC652 Datasheet | Motorola Semiconductor

.. MC74AC652 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 Choice of True and Inverting Data Paths 3-State Outputs 300 mil Slim Dual-in-Line Package Outputs Source/Sink 24 m A ′ACT652 Has TTL patible Inputs REAL TIME TRANSFER A-BUS TO B-BUS A-BUS REG B-BUS REG REG B-BUS REAL TIME TRANSFER B-BUS TO A-BUS A-BUS REG 24 1 MC74ACT652 OCTAL TRANSCEIVER/ REGISTER WITH 3-STATE OUTPUTS (NON-INVERTING) 24 1 N SUFFIX CASE 724-03 PLASTIC PACKAGE Figure 1 STORAGE FROM BUS TO REGISTER A-BUS REG B-BUS REG REG Figure 2 TRANSFER FROM REGISTER TO BUS A-BUS REG B-BUS DW SUFFIX CASE 751E-04 SOIC PACKAGE PIN NAMES A0 - A7 B0 - B7 CAB, CBA SAB, SBA GAB, GBA Data Register A Inputs Data Register A Outputs Data Register B Inputs Data Register B Outputs Clock Pulse Inputs Transmit/Receive Inputs Output Enable Inputs Figure 3 MAXIMUM RATINGS- Symbol VCC Vin Vout Iin Iout ICC Tstg Figure 4 Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Sink/Source Current, per Pin DC VCC or GND Current per Output Pin Storage Temperature Value - 0.5 to +7.0 - 0.5 to VCC + 0.5 - 0.5 to VCC + 0.5 ± 20 ± 50 ± 50 - 65 to +150 Unit V V V m A m A m A °C - Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the Remended Operating Conditions. FACT DATA Data...
