Filed: 1989-04-20
Abstract: PURPOSE:To prevent an operational speed from being lowered by the incidental capacity of a phase inversion control circuit by selecting and operating any one of a pair of differential current switch circuits by the phase inversion control circuit. CONSTITUTION:A pair of differential current switch circuits 6 and 7 are composed of first and second transistors, whose emitters are commonly connected, and a constant current source connected to the emitters of these transistors and parallelly provided to output complementary signals, whose phases are mutually inverted, on the basis of the same input signal A. Any one of these switch circuits 6 and 7 is selected and operated by a phase inversion control circuit 10 to be operated on the basis of a phase control signal C. Next, the output signals of the switch circuits 6 and 7 are outputted through an output level shift circuit 4. Accordingly, since the phase inversion control circuit 10 is not interposed between the switch circuits 6 and 7 and the level shift circuit 4, the phase inversion control circuit 10 is not the incidental capacity to the switch circuits 6 and 7.
