Abstract: PURPOSE:To realize at least two kinds or more of output drive circuits having defferent load driving characteristics on an integrated circuit device by changing the width of gate electrodes in P channel type and N channel type field-effect transistors constituting the output drive circuits in at least two kinds or more. CONSTITUTION:42 in an output drive circuit A represents an input terminal and 43 a power supply terminal. Q1,Q3 represent P channel field-effect transistors and Q2,Q4 N channel field-effect transistors, and are connected mutually, thus constituting a known inverter. The size width and length of gate electrodes in the field-effect transistors Q3, Q4 as final output stages are determined to W and L respectively. Q5, Q6 in an output drive circuit B represent P and N channel type field-effect transistors as final output stages. Accordingly, circuit constitution itself is the same in both the output drive circuits A, B, but the width of a gate electrode in the field-effect transistor Q5 is reduced to 0.6 times (0.6W) and the width of a gate electrode in the field-effect transistor Q6 to 0.3 times respectively (the same as the length of the gate electrodes), and each ON resistance is increased to 1.5 times and treble of the corresponding field-effect transistors Q3, Q4 in the output drive circuit A.
