Input/output buffer for an integrated circuit.

摘要

An integrated circuit includes an input buffer circuit (1) and an output buffer circuit (2). The source voltage to the input buffer circuit and the output buffer circuit are supplied through bonding pads (4, 11) fromed independently on a semiconductor chip, and electrically connected to a source potential lead pin (N4). The input node (N5) of the input buffer circuit (1) is coupled to the source potential (VSS min ) of the output buffer circuit with a capacitor (C).
