‪
-What type of circuit is shown in Figure 15- 2, and how is the output ordinarily connected?

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