PURPOSE:To select a CMOS or a TTL by arranging the CMOS and the TTL on an output part and changing the connection of an aluminium wire in accordance with the size of an external load. CONSTITUTION:The output of a CMOS gate 4 in an internal logical circuit area is used for executing aluminium connection changing processing 6 through an aluminium pattern 5 and then connected to the input of a TTL gate 7 and the output of the TTL gate 7 is used for executing aluminium modifying processing 8 through the aluminium pattern 5 and then connected to a bonding pad 9. Since a CMOS gate 10 is not connected to the output of the CMOS gate 4 and the bonding pad 9, no logical signal is received/transmitted. Consequently, the CMOS gate or the TTL gate can be selected in accordance with the size of the external load. |
