PURPOSE:To attain stable circuit threshold value and low power consumption by connecting a P-channel enhancement MOS transistor (TR) acting like a constant current source to a load of a CMOS inverter circuit. CONSTITUTION:The circuit has a P-channel enhancement MOSTRQ5, an N-channel enhancement MOSTRQ6, and an N-channel enhancement MOSTRQ7 and the TRs Q5, Q6 and Q7 are connected in series between a power terminal 15 to which a power voltage VDD is impressed to ground. Further, a connecting point between the TRs Q6, Q7 is connected to a gate of the TRQ6 and an output signal voltage VOUT is obtained from a connecting point between the TRs Q6, Q7. Further, the position of the MOSTRs Q5, Q6 is replaced in the other executing mode. |
