Abstract
A driver circuit is provided, which has output characteristics capable of satisfying the DC and AC LVDS standards even if the power source and temperature fluctuate, has LVDS output characteristics, can reduce the number of outside components, and allows a dense package mounting. This driver circuit is constituted by connecting four NPN bipolar-type transistors and three resistors; four input signals are respectively input into base portions of these four NPN bipolar-type transistors; the first input signal and the second input signal have the same DC and AC levels but their phases are reversed, the third input signal and the fourth input signal have the same DC and AC levels but their phases are reversed; and the first input signal and the fourth input signal have the same phase, and the second input signal and the third input signal have the same phase.
