DRIVER CIRCUIT, DIFFERENTIAL TRANSMITTER USING THE SAME, ELECTRONIC APPARATUS, AND INDUSTRIAL APPARATUS

Japanese Patent JP2015019160

A

PROBLEM TO BE SOLVED: To suppress the effects of backflow preventing diodes.SOLUTION: A first PMOS transistor MP11 and a second PMOS transistor MP12 are disposed between a power line LVCC and an output terminal OUT, and a first NMOS transistor MN11 and a second NMOS transistor MN12 are disposed between the output terminal OUT and a ground line LGND. A source of a third PMOS transistor MP13 is connected to the output terminal OUT, and a gate thereof is biased by a first bias circuit 20 so as to be turned on when VOUT>VH. A source of a third NMOS transistor MN13 is connected to the output terminal OUT, and a gate thereof is biased by a second bias circuit 30 so as to be turned on when VOUT
