MC74AC652, MC74ACT652 Octal Transceiver/Register with 3−State Outputs (Non−Inverting) 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. • • • • • • • w 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 http://onsemi.com PDIP−24 N SUFFIX CASE 724 24 1 SO−24 DW SUFFIX CASE 751E 24 1 MARKING DIAGRAMS PDIP−24 These devices are available in Pb−free package(s).
