Abstract
An input buffer provides buffering of digital input signals and noise filtering. The input buffer includes a Schmitt trigger having a fast response to digital signal rising edges and a slow response to digital signal falling edges. A first transfer gate having a relatively slow response conveys rising edge transitions to the Schmitt trigger and a second transfer gate having a relatively fast response conveys falling edge transitions to the Schmitt trigger.
