Abstract
An input buffer includes a low-speed input buffer for buffering an input signal at the time of low-speed operation, a high-speed input buffer being controlled by the low-speed input buffer, for adjusting the high-level and low-level logic of an input signal at the time of high-speed operation and an output driver for outputting high-level or low-level logic by inputting the output signal of the high-speed input buffer. Therefore, there is no direct current present, the operational speed is increased and noise can be reduced.
