Connect the gates directly to 3,3v, the sources via a 10k resistor to 3,3v and the drains via a 10k. Can convert between 1.8v, 2.8v,. Web this is called logic level shifting.
Web Logic Level Converter Bidirectional.
Level shifting is a dilemma so common we designed a simple pcb assembly to make interfacing devices a little easier: In this item, you will learn: There is not much to tell about te construction of this circuit.
The Power Consumption Is Easy To Estimate:
