ABSTRACT:
A data communication device includes a first antenna; a semiconductor circuit for generating signals for use in outputting communication data through the first antenna, the semiconductor circuit having a CMOS configuration of a combination of a P-channel MOS transistor and an N-channel MOS transistor on a single chip; and an antenna connection circuit through which the semiconductor circuits is connected to the first antenna. The semiconductor circuit includes a power-supply-connecting MOS drain output part and a ground-connecting MOS drain output part. The antenna connection circuit has a first electric element for inhibiting a current from flowing into the corresponding semiconductor circuit in the power-supply-connecting MOS drain output part.
