    What type of circuit is shown below, and how is the output ordinarily connected? It is an open-colle


  • Options
  • A. It is an open-collector gate and is used to drive loads that cannot be connected directly to Vcc due to high noise levels.
  • B. It represents an active-LOW inverter and is used in negative logic systems.
  • C. It is an open-collector gate. An external load must be connected between the output terminal and an appropriate supply voltage.
  • D. Any of the above could be correct, depending on the specific application involved.

  • Correct Answer
