Abstract

PURPOSE:To accelerate the switching speed of the circuit by providing level shifting means and clamping means in a TTL used as an internal circuit, and reducing the potential differences between the threshold value voltage and low potential output voltage, and between the threshold value voltage and the high potential output voltage respectively. CONSTITUTION:The base of a multi-emitter transistor Q1 connected with the emitter at input ends in1 and in2 is connected through a resistor R1 to a power source Vcc, and the collector thereof is connected to the base of a transistor Q2. Then, the collector of the transistor Q2 is also connected through a resistor R2 to the power source Vss. A Schottky barrier diode D1 which is clamping means is connected between the transistors Q1 and Q2, and a diode D2 is connected between the base of the transistor Q2 and the collector. Furthermore, the emitter of the transistor Q2 is connected to the base of the transistor Q3 to form a Darlington circuit, and a level shifting diode D3 is connected between the collector of the transistor Q3 and that of the transistor Q2. A diode D7 which is clamping means is provided between the emitter of the transistor Q2 and the base of the transistor Q3, and an output (out) is led out from the above diode.
