ABSTRACT:
In normal operation, an internal circuit operates in synchronism with a clock CK, so that switching operation of the output circuit is performed based on inputted data and an output enable signal. At this point, an output from the internal circuit to a three-state control circuit is forcedly set by state control circuits, whereby different test operations are performed on the output circuit.
