Abstract
A programmable logic device has buffers that may be selectively programmed for Schmitt-triggered and threshold-triggered operation. The programmable Schmitt-triggered buffers are connected to circuit nodes that are sensitive to noisy environments. The programmable threshold-triggered buffers are connected to circuit nodes that have critical timing requirements.
