#108510 - ULN2003's doesn't easily burn Responding to: ???'s previous message |
Personaly , I use SMDs and I try to place them near to the relays. But in a sensitive situation there is no other way than placing a fast recovery diode right at the realy's coil pins.
These darlington drivers donot easily brun (when tarnsistors do),So I like them more. Farshid |

| 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 | |

| Bad Design? | 01/01/70 00:00 | |

| Also depends on transistor speed | 01/01/70 00:00 | |
