Logic Level Shifter Schematic. 757 because the arduino and basic stamp are 5v devices and most modern sensors displays flash cards and modes are 3 3v only many makers find that they need to perform level shifting conversion to protect the 3 3v device from 5v we do have some other handy. In the schematic below i use a classical setup for a logic level shifter.

When lx is driven low the mosfet turns on and the zero passes through to hx. When hx is driven low lx is also driven low.
Schematic diagram the logic level conversion is accomplished with a simple circuit consisting of a single n channel mosfet and a pair of 10 kω pull up resistors for each channel.
Adafruit industries unique fun diy electronics and kits 4 channel i2c safe bi directional logic level converter bss138 id. Schematic diagram the logic level conversion is accomplished with a simple circuit consisting of a single n channel mosfet and a pair of 10 kω pull up resistors for each channel. The top row consists of high voltage supply and ground pins hv and gnd and 4 high voltage channels hv1 hv2 hv3 and hv4. A logic level shifter or a voltage level translator is used to translate signals from one logic level to another.
