  • CMOS input circuit for providing logical output signal from TTL compatible input signal
    Patent number: 5455520
    Abstract: An input circuit having a CMOS component which outputs correct logical values without through-current flowing when a high level logic output signal V.sub.OH at TTL level is input thereto. The input circuit 1 comprises inverter 20 which outputs by logically inverting the input signals and through-current prevention circuit 21 which stops the flow of current to inverter 20 from power supply V.sub.CC. The through-current prevention circuit 21 comprises reference voltage generating circuit 10, inverters 12 and 13, and MOS transistors 11a, 11b, 14, and 15. The threshold value voltage of inverter 12 is set slightly lower than the high logic level output V.sub.OH at TTL level, and the threshold value voltage of inverter 20 is set lower than inverter 12.
