ABSTRACT:
An improved static metal oxide semiconductor (MOS) input circuit having particular utility as a TTL input receiver, is fabricated from enhancement and depletion-type field effect transistors (FETs). The input circuit is adapted to produce positive feedback to adjust the on-resistance ratios of some of the circuit transistor devices, whereby hysteresis is developed. By virtue of the hysteresis, an extended noise margin is provided at the circuit input terminal so that MOS logic level output signals are clearly distinguishable from one another at the circuit output terminal.
