hi,
Alberto Geraci said:
If you have a 3.3V system it's NOT a TTL compatible system, currents are differents, fan-outs are differents, a lot of parameters are differents, and the most important...Logic Levels are differents !!! For me, there is yet another important thing called "latchup" which destroys a chip completely. Read this thread: http://www.8052.com/forum/read.phtml?id=75866 Regards, Oleg |

| 3.3 Volts logic with 5V input ? | 01/01/70 00:00 | |
| LPC9xx has it !! | 01/01/70 00:00 | |
| OK TTL is now =xxV | 01/01/70 00:00 | |
| LPC9xx and 5V | 01/01/70 00:00 | |
| not beginners but ignorami | 01/01/70 00:00 | |
| Begginers or not | 01/01/70 00:00 | |
| well, look here | 01/01/70 00:00 | |

| Cygnal Has It !! | 01/01/70 00:00 | |
| Cygnal and LPC9xx | 01/01/70 00:00 | |
| Incompatible? | 01/01/70 00:00 | |

| 5V tolerant. | 01/01/70 00:00 | |
| Relax! | 01/01/70 00:00 | |
| OK is only for Rigo | 01/01/70 00:00 | |
| No more logic levels | 01/01/70 00:00 | |
| Logic Lines Not Hard Lines | 01/01/70 00:00 | |
| Only one answer possible. | 01/01/70 00:00 | |
