Sorry Erik , I am a little busy these days , I am glad you found it by yourself. That I have seen that "the chip still works" does not mean that I recommend overloading such chips. Neither do I recommend that. I just wanted to say using a ULN would be a more reliable option like using a 74HC buffer. 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 | |
