IPC: H03K19/0175
Filed: 1987-10-23
Abstract: PURPOSE:To identify a level of an input signal by allowing a comparator circuit to have a higher threshold value by a prescribed voltage than the reference power voltage and giving a prescribed voltage from the output circuit only when the input voltage exceeds the threshold value. CONSTITUTION:A comparator circuit 2 has a value higher than a reference voltage VREF given by a reference power supply 1 by a prescribed voltage only as the threshold value Th and when the input voltage Vin is lower than the threshold value Th, no output voltage is given to the output circuit 3, but when the input voltage Vin is higher than the threshold value Th, a current is supplied to the output circuit 3 to generate a prescribed voltage.
