Question
A logic probe is placed on the output of a gate and the display indicator is dim. A pulser is used on each of the input terminals, but the output indication does not change. What is wrong?
Options
A. The output of the gate appears to be open.
B. The dim indication on the logic probe indicates that the supply voltage is probably low.
C. The dim indication is a result of a bad ground connection on the logic probe.
D. The gate may be a tristate device.

Correct Answer

The output of the gate appears to be open.
