Abstract

PURPOSE:To accelerate response speed, by discharging an electric charge accumulated in a load capacitance by a transistor when an internal output level in an ECL circuit falls from a high level to a low level. CONSTITUTION:The bases with the same polarity in complementary type transistors consisting of transistors Q11 and Q13, and Q12 and Q14 are connected with each other. When the voltages in a forward direction of the base and the emitter of the transistor are equal, an output terminal 13 is set at the same high level state as an input terminal 11, and charging to the load capacitance CL at the output terminal 13 is performed by the transistor Q12. When potential at the input terminal 11 drops to the low level, a voltage larger than the voltage VF in the forward direction applied on the base and the emitter ordinarily is applied between the base and the emitter of the transistor Q14, and as a result, the electric charge accumulated in the load capacitance CL is discharged by the transistor Q14, and output falls steeply.
