Boosted supply output driver circuit for driving an all N-channel output stage |
摘要 |
An output driver circuit includes first and second translator circuits and a boosted voltage generator. The output driver circuit is suitable for driving the first and second inputs of a reduced voltage N-channel output stage. The first and second translator circuits each have a power terminal and an input for receiving first and second logic input signals. A boost voltage generator having a boosted voltage output is respectively coupled to the power terminals of the first and second translator circuits. The first translator circuit has an output coupled to the first input of the N-channel output stage for providing a boosted logic output signal in a logic high polarity state. The second translator circuit has an output coupled to the second input of the N-channel output stage for providing a boosted logic output signal in a logic high polarity state. The outputs of the first and second translator circuits are complementary for driving the N-channel output stage to provide a valid output logic signal. Alternatively, the outputs of the first and second translator circuits are both low for placing the N-channel output stage into a high impedance tristate mode.
