John: The above 2 pictures are called the circuit of Tri State Buffer. The concept of the circuit of Tri State Buffer originate from the circuit of "Inverter". You may have a look at this article ( https://wodewangzhishime.blogspot.com/2022/06/what-does-he-need.html ). It is about the circuit of Inverter.
Me: OK.
John: The Symbol of the circuit of Tri state control look like a Triangle.
Me:OK.
John: OK, before we start this article, you may read this article (https://wodewangzhishime.blogspot.com/2022/02/httpswodewangzhishime_25.html).
Me: OK.
John: Now, I explain the 1st picture in code.
.
If (output control = Up cycle)
{
The current tend to flow outside.
Output is available.
}
John: Now, I use code to explain the 2nd picture.
If (output control = down cycle)
{
The current tend to flow inside.
Output is disabled.
}
