The MC74AC646/74ACT646 consist 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 the following figures.
Features
 
  • 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
  • ACT646 Has TTL Compatible Inputs
  • These devices are available in Pb-free package(s). Specifications herein apply to both standard and Pb-free devices. Please see our website at www.onsemi.com for specific Pb-free orderable part numbers, or contact your local ON Semiconductor sales office or representative.
