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 mA ′ACT652 Has TTL Compatible Inputs
