- In digital electronics, a level shifter, also called logic-level shifter or voltage level translator, is a circuit used to translate signals from one logic level or voltage domain to another,
- allows compatibility between integrated circuits with different voltage requirements, such as TTL and CMOS.
- A level shifter translates logic signals from one level to another.
- Usually, this shift takes place between 5V and 3.3V, but you can use other voltages as needed, such as 2.5V or 1.8V.
