The level converter is used for level adaptation between MTL/I/2/L circuits and ICSL (Injection Current Switch Logic) circuits. ICSL circuits are based on a standard current switch. Their power supply, similar to MTL/I/2/L, is effected by PNP transistors associated with and feeding the bases of NPN switching transistors.
