#148739 - these superfluous facts in the datasheet Responding to: ???'s previous message |
the datasheet will tell you max and min Ioh, Iol, Voh, Vol, Iih, Iil, Vih, Vil.
These values are ignored by most ("a high is a high, a low is a low") Then, on the other hand, those of us that actuially apply those values have a tendency to make succesful designs, I wonder why. Erik |

| 8051 Port Pin wont go low | 01/01/70 00:00 | |
| Try this | 01/01/70 00:00 | |
| here is the schematic | 01/01/70 00:00 | |
| RC-reset is wrong! | 01/01/70 00:00 | |
| That RST schematic is for AVR , which | 01/01/70 00:00 | |
| yes schematic shows wrong reset | 01/01/70 00:00 | |
| Low state current | 01/01/70 00:00 | |
| I tried this | 01/01/70 00:00 | |
| You should use CMOS | 01/01/70 00:00 | |
| here is the code | 01/01/70 00:00 | |
| signal source is inadequate, code is irrelevant | 01/01/70 00:00 | |
| The 7407 has the same problem ... | 01/01/70 00:00 | |
| would this work? | 01/01/70 00:00 | |
| why not 'H' why 'HC"? | 01/01/70 00:00 | |
| its what I have | 01/01/70 00:00 | |
| H ??? Didn\'t they quit making that in the \'70s? | 01/01/70 00:00 | |
| 74HC04 is working | 01/01/70 00:00 | |
