  • Electrostatic discharge protection circuit and method
    Patent number: 6118323
    Abstract: An integrated circuit includes a voltage supply internal to the integrated circuit and circuitry for sensing the voltage level of the internal voltage supply, the circuitry responsive to produce a flag signal, VPUEN, that is in a first logical state when the voltage level is below the desired level and in a second logical state when the voltage level is above the desired level. The integrated circuit also includes a buffer driver 406 having an input terminal and an output terminal, the input terminal being coupled to the circuitry for sensing the voltage level of the internal voltage supply. The operation of the circuit is such that the output terminal 400 of the buffer driver is in a high-impedance state when the flag signal is in the first logical state, and is responsive to data signals on the input terminal to produce corresponding output signals at the output terminal when the flag signal is in the second logical state.
