When an open occurs on the input to a bipolar logic device, the output will _________ .
A) go LOW, because there is no current in an open circuit
B) go HIGH, since full voltage appears across an open
C) react to the open input as if it were a HIGH input
D) still be good, if only the good inputs are used

Quizplus · Accepted Answer

In bipolar logic devices, an open input is typically interpreted as a HIGH input due to the pull-up resistors or the default high state of the input circuitry.
