#124495 - No, it does not Responding to: ???'s previous message |
Eric, what you said was that I was incorrect for stating I used an AND gate to acheive a low output when any givien input goes low. By the definitions I've read of an AND gate, that's what exactly I should be using. Additionaly, it works.
The datasheet for the thing calls it an AND gate. I found it by searching for an AND gate. I bought it due to its being marketed as an AND gate. And it works as an AND gate. No, it does not, it detects ANY key pressed (ANY is the definition of an OR). If you read up on Boole, you would find that while the 'logic' is the same for a positive AND and a negative OR, the reason for the function is totally different. positive AND = ALL in high = high out negative OR = ANY low in = low out. Yes, the electronocs are the same, but the reason for using it is different. as said, it will eventually lead to confusion using the wrong terminology. That being said, you were right about this glad to be of help Erik |
