I need to change 3 signals (I1,2,3) which will be at around 2V to get shifted to 5V (in one direction only to O1,2,3). This schematic should do the job, but does anyone know if:
a) there's a better way to do it?
b) there's an IC which does this in a single package?
The way it works is: to set an output (O1-3) to low, the pin connected to the corresponding input (I1-3) should be pulled to anything below about 3.5V, to set it high, the pin should be floated. It works on a breadboard and seems to be the simplest way I can think of to do it.
The power consumption will be very small, a few milliamps. Oh, and these are P style MOSFETS.
