Octal Bus Transceivers

Octal Bus Transceivers - SN74BCT245


These octal bus transceivers are designed for asynchronous communication between data buses. The devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending upon the level at the direction-control (DIR) input. The output-enable (OE)\ input can be used to disable the device so the buses are effectively isolated.


  • 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
  • ESD Protection Exceeds JESD 22
    • 2000-V Human-Body Model (A114-A)
