hello i want to connect 8 12v relays with atmel 89c51 port p0 can you help about the circuit diagram which help me to connect relay with the port p0. How much current is drawn by each relay? Kai |

| Just search for, "Relay" !! | 01/01/70 00:00 | |

| ULN2803,ULN2003 | 01/01/70 00:00 | |
| more on relay ratings | 01/01/70 00:00 | |
| Yes of course | 01/01/70 00:00 | |
| internal diodes | 01/01/70 00:00 | |
| ULN2003's doesn't easily burn | 01/01/70 00:00 | |
| Uce saturation voltage is rather high | 01/01/70 00:00 | |
| there is an alternative, search for it | 01/01/70 00:00 | |
| I agree | 01/01/70 00:00 | |
| That is bad design | 01/01/70 00:00 | |
| ULNs resist more... | 01/01/70 00:00 | |
| I would never suggest 74HC buffers for d | 01/01/70 00:00 | |
| Yes , you didn't | 01/01/70 00:00 | |
| I would like to see where that is, pleas | 01/01/70 00:00 | |
correct link | 01/01/70 00:00 | |
| Bad Design? | 01/01/70 00:00 | |

| Also depends on transistor speed | 01/01/70 00:00 | |
| valid issue, but not that, now another | 01/01/70 00:00 | |
| Indeed | 01/01/70 00:00 | |
