The LS2 level shifter converter is a small module that allows a 3.3V or 5V microprocessor such as an Arduino to drive a 12V signal. This level converter has two supply voltages, one on the left side of the module and one on the right hand side of the module. The left hand side of the module has the input pins and the right hand side has the output pins. The input voltage signals can be higher or lower than the output signals. If the input voltage is lower than the output supply voltage the module increases the size of the output signals. If the input supply voltage voltage is higher than the output supply voltage the module reduces the size of the output signal.
Each LS2 module can convert or buffer 12 signals.
