| Oct 14 at 11:22 | comment | added | Davide Andrea | >the two transistor could also be swapped with diode. No, that's not what I meant. sorry for the confusion. What I meant was " you only need Q1 and Q3 with the gates to ground. The rest of the circuit is not needed for 5 V". I don't know how to say it more clearly than that. | |
| Sep 27 at 18:35 | comment | added | Tyassin | Ok i see. So basically the two transistor could also be swapped with diode and have the same function? | |
| Sep 27 at 12:50 | comment | added | Davide Andrea | To operate in a wide range of voltages. OP doesn't have that requirement because it's a 5 V circuit. | |
| Sep 27 at 9:23 | comment | added | Tyassin | A question. What are the purpose Q2A and Q4B in general for this Circuit? | |
