<p class="hcp2">A logic NOR gate takes two or more logic-level
|

inputs and produces a single logic-level output. The NOR gate behaves
|
||
|
|
according to the truth table below. The output of the NOR gate will be

LOW (0) when any input is HIGH (1). The output will be HIGH (1) only when

all inputs are LOW (0).</p>
