Logic Level Converter Schematic. The top row consists of high voltage supply and ground pins hv and gnd and 4 high voltage channels hv1 hv2 hv3 and hv4. When hx is driven low lx is also driven low.
3v3 5v i2c logic level converter schematic. In this article we are about to see a logic level converter which converts 5v to 3 3v and vice versa. A simple logic level converter can also be built using resistive voltage dividers but it will introduce voltage loss.
To deal with this we use special circuits called as logic level converters.
The circuit uses an n channel mosfet to convert the low voltage logic level to a high voltage logic level. These circuits are capable of converting 5v to 3 3v and 3 3v to 5v successfully thus bridging the chip ttl and cmos chip families. The improvements include on board 3 3 low drop voltage regulator direction selection jumpers easy to use input output terminals and power on indicator led. The top row consists of high voltage supply and ground pins hv and gnd and 4 high voltage channels hv1 hv2 hv3 and hv4.
