Abstract
An input translating circuit for a CMOS device is disclosed which can be operated without being influenced by a level of the supply voltage. This is made possible by providing a supply voltage level discriminating means consisting of a voltage dividing network for dividing the supply voltage into predetermined voltages and a level comparing means for comparing the divided voltage with the reference voltage level, and further by providing a constant voltage supply means, so that a trip voltage, used in the operation of the circuit, can be maintained at a constant level regardless of the variations of the supply voltage. Further, the circuit according to the present invention eliminates corresponding mask work requirements for the option of the power voltage in the manufacturing process, thereby lowering production complexity costs.
