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 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 MC74AC652 MC74ACT652 OCTAL TRANSCEIVER/ REGISTER WITH 3-STATE OUTPUTS (NON-INVERTING) 24 1 N SUFFIX CASE 724-03 PLASTIC PACKAGE 24 1 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 ……
