ABSTRACT:
In a push-pull output circuit comprising inverters, each using a depletion-type load field-effect transistor (FET) and an enhancement-type driving FET, an intermediate inverter including a depletion-type load FET and an enhancement-type driving FET is added between the input side and output side inverters. The load impedance of the output side inverter is set at a value much smaller than those of the other inverters. The utilization of a power supply voltage is enhanced because of the use of depletion-type FET's and the total current in the circuit is low due to the use of the intermediate inverter.
