  • CMOS logic circuit with output coupled to multiple feedback paths and associated method
    Patent number: 5151622
    Abstract: A TTL to CMOS input buffer circuit is provided which includes a level shifting circuit including an input terminal and an output node for receiving at the input terminal an input signal at a TTL logic voltage level and for providing at the output node an output signal at a CMOS logic voltage level, the output signal being a logically inverted version of the input signal; and a first circuit for speeding a transition of the output signal from a low CMOS voltage level to a high CMOS voltage level; and a second circuit for preventing the first circuit from interfering with a transition of the output signal from the high CMOS voltage level to the low CMOS voltage level.
