ABSTRACT:
Comparison circuits are provided, corresponding to a plurality of pull up transistors, each for comparing a voltage at an output node and each respective reference voltage different in voltage level from other, and for adjusting a drive current of a corresponding output pull up transistor, and further comparison circuits are provided, corresponding to a plurality of pull down transistors, each for comparing the voltage of the output node and each respective reference voltage different in voltage level from other, and each for adjusting an amount of a drive current of a corresponding pull down transistor in accordance with a result of comparison. The reference voltages each are set to a voltage level between a power supply voltage and a ground voltage. Without a dedicated power supply pin terminal, a signal of a small amplitude having the amplitude limited stably and precisely can be output at high speed.
