Abstract

An output buffer circuit drives an output terminal of an integrated circuit by means of at least two buffer circuits. A buffer control circuit in the output buffer circuit selectively enables or disables the buffer circuits to provide a driving capability suitable for the load connected to the output terminal. The buffer control circuit can decide which buffer circuits to disable by sensing the transition time of a signal output from the output terminal following a reset.
