For an NPN open emitter output, the collector is connected to the positive voltage rail, so the emitter outputs a high voltage when the transistor is on and is hi-Z when off. For a PNP open emitter output, the collector is connected to the low voltage supply, so the emitter outputs a low voltage when the transistor is on and is hi-Z when off.
Luanti (formerly and colloquially Minetest) is a free and open-source voxel game creation system.It is written primarily in C++ and makes use of the Irrlicht Engine. Luanti has a Lua API allowing users to write their own games and mods.
The heart of an I2L circuit is the common emitter open collector inverter. Typically, an inverter consists of an NPN transistor with the emitter connected to ground and the base biased with a forward current from the current source. The input is supplied to the base as either a current sink (low logic level) or as a high-z floating condition ...
The transistor continuously monitors V diff and adjusts its emitter voltage to equal V in minus the mostly constant V BE (approximately one diode forward voltage drop) by passing the collector current through the emitter resistor R E. As a result, the output voltage follows the input voltage variations from V BE up to V +; hence the name ...

English: Two inputs are connected to open-collector buffers. If a buffer's input is high, the buffer will be in a high-impedance output state. If a buffer's input is low, the buffer will connect to ground. If all inputs are high, the output will be pulled high by the pull-up resistor.
