ABSTRACT:
An input buffer for semiconductor integrated circuits has a resistor (16), capacitor (17) and a logical gate comprising transistors (11, 12, 13) connected in series between a supply line (61) and a ground line (62). The resistor (16) reduces the through current which flows toward the ground (Vss) when the logical gate switches. In a high speed operation, the capacitor (17) supplies current to the logical gate so that any delay which may possibly be caused by the provision of the resistor (16) can be prevented.
