Title: Input level conversion circuit
Inventor: HATANO TAKAHIRO
IPC: H03K5/003
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To prevent malfunctions due to the transition of a node potential inside a DC reproducing circuit by level-converting input signals whose amplitude is from a low potential to a prescribed high potential to output signals whose amplitude is from the low potential to the high potential lower than the high potential. SOLUTION: In the case that the input signals are not changed for a long time, in the DC reproducing circuit 31, the potential of the node in the inside is surely shifted to the potential of a high potential power source and thus, the output signals of an input level conversion circuit LC1 are inverted with the input signals. Corresponding to it, normally, the output signals of the circuit 31 are turned to the output signals of the conversion circuit LC1, however, an NOR circuit 13 is provided so as to output the output signals of a limiter circuit 30 as level conversion signals regardless of the output level of the circuit 31 only in the case that the input signals of the circuit LC1 are not changed for a long time and the potential of the node inside the circuit 31 is shifted to the potential of the high potential power source.  Thus, the malfunctions due to the transition of the potential of the node inside the circuit 31 are prevented.
