Abstract
An integrated circuit ('IC') includes an input receiver with multiple hysteresis levels. An exemplary input receiver may be an input buffer with a Schmitt trigger that has multiple hysteresis windows between different high and low input voltages. This circuit may improve the input noise immunity of the external input signals and timing by allowing for a selection one of the plurality of levels depending on parameters of the input (e.g. noise level).
