Summary:An input buffer circuit includes a first differential circuit, a second differential circuit, a pull-up circuit, and a pull-down circuit. An input voltage and a reference voltage are provided to the first and second differential circuits. The first differential circuit detects rising edges of the input voltage and causes the pull-up circuit to quickly drive an output voltage to logic high. The second differential circuit detects falling edges of the input voltage and causes the pull-down circuit to quickly drive the output voltage to logic low.
