Each unit can invert a incoming clock, please not the logic state is inverted, not the voltage value like on a voltage inverter. "high" becomes "low" and vice versa.
Additionally it generates a short trigger impulse of 50ms at each trigger edge - no matter if rising of falling.
per unit: two inputs, inverted output, +/- output
