Abstract

This invention contemplates the provision of a noise immune integrated circuit receiver in which the voltage reference to one side of an emitter-coupled current switch moves in response to the input signal, in a direction opposite the input signal. This provides the gate with a threshold hysteresis, making it immune to noise without requiring a large swing in input signal.
