When an open occurs on the input of a CMOS gate, the output will _________ .
A) be treated as if the open input were a HIGH
B) go LOW, because there is no current in an open circuit
C) go HIGH, since full voltage appears across an open
D) be unpredictable; it may go HIGH or LOW

Quizplus · Accepted Answer

When an open occurs on the input of a CMOS gate, the output behavior becomes unpredictable due to floating inputs. This can cause the gate to interpret the input as either high or low, depending on the specific conditions such as leakage currents or static electricity.
