Abstract
In an input buffer, logic level discrimination is provided by a first circuit which provides a first current to the output so that the output voltage is a hysteresis function of the input volt. To improve transient response without increasing power consumption, a second circuit is used to provide a second current to the output in support of the first current during transient periods of the input signal.
