  • Semiconductor integrated circuit having tri-state logic gate circuit
    Patent number: 6133752
    Abstract: The tri-state logic gate circuit is preferably made up of a first inverter circuit which selectively outputs one of the power supply voltage and a ground potential, a second inverter circuit which selectively outputs one of the first inverter circuit output and the boosted power supply voltage, a resistor connected between the first and second inverter circuits, and a latch circuit. Accordingly, the tri-state logic gate circuit can avoid latch-up.
