|
<p class="hcp1">A logic AND gate takes two or more logic-level
|
||
|
inputs and produces a single logic-level output. Because the output is
|
||
|
also a logic level, an output of one logic gate can connect to the input
|
||
|
of one or more other logic gates. Two outputs cannot be connected together,
|
||
|
however, as they may be attempting to produce different logic values.
|
||
|
The AND logic object is a digital logic gate that implements logical conjunction
|
||
|
- it behaves according to the truth table below. A HIGH output (1) results
|
||
|
from both the inputs to the AND gate being HIGH (1). If neither or only
|
||
|
one input to the AND gate is HIGH, a LOW output results.</p>
|
||
|
<p class="hcp1">The lights on the logic object design block
|
||
|
indicate the current state of the inputs and output. These are operational
|
||
|
in simulation and when online to the device.</p>
