ABSTRACT:
Circuit for converting input signals at TTL voltage levels to output signals at voltage levels for use with MOS logic circuits. The circuit employs an arrangement of NMOS FET's. Six FET's are arranged in pairs to form three inverters. Another FET is connected in series between the input terminal and different portions of the first and second of the three inverters. The output of the second inverter is fed back to the gate electrode of one of the FET's of the first inverter and to the gate electrode of the series connected FET. The output of the second inverter is also applied to the third inverter. The excursion between voltage levels representing logic 1 and logic 0 at the output of the third inverter is greater than the excursion between voltage levels representing logic 1 and logic 0 at the input to the circuit.
