Abstract
An interface input has an input circuit adapted to receive input signal levels higher than a maximum signal level that a host circuitry's electronic components can reliably handle. The input circuit shifts the level of the input signal to a desired signal level. A keeper circuit is coupled to the input circuit and maintains trigger levels of the shifted signals consistent with the input signal level.
