<p>The present invention provides a logic circuit comprising a current control means (5) including first (P1) and second MOS transistors (P2) for controlling the current to the output circuit (1) and also for controlling the output wave form, in accordance with the input signal (A, B) and the output signal. When the output signal rises from a low level to a high level, a large current is supplied to the output circuit to obtain a steep rise. When the output signal is high level, the current to the output circuit becomes small, and the power consumption is reduced.</p> |
