Logic Level Converter Schematic. 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. 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.
Schematic of the logic level converter circuit 74lcx245 datasheet the presented circuit features improvements that set it apart from other published logic level converter circuits. The top row consists of high voltage supply and ground pins hv and gnd and 4 high voltage channels hv1 hv2 hv3 and hv4. 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.

Schematic of 4 channel logic level converter if you take a look at the image of a typical 4 channel level shifter module it consists of 12 pins in two rows. Board overview if you take a peek at the board s schematic you d find that the bi directional logic level converter let s shorten that to bd llc is actually a very simple device.
