ABSTRACT:
An I/O circuit is capable of achieving a reduction of power consumption by preventing leak current while performing the pull-down or pull-up operation. The I/O circuit of the present invention is constructed so that an I/O terminal 5 is pulled down or pulled up only when the I/O terminal 5 is in an open state or at the same potential as the pull-down or pull-up potential provided to the I/O terminal 5 when the high impedance state is input to the I/O terminal 5. The I/O circuit comprises an output circuit providing tri-state outputs, a switch circuit for the pull-up or pull-down operation, and an input circuit connected to the I/O terminal, the switch circuit and internal circuits of a device.
