    摘要: An electrostatic discharge protection circuit is provided with a variable threshold for limiting the potential of an input signal having a given high or low voltage, and is adapted to an EPROM containing an input MOS transistor which is responsive to the input signal. The protection circuit is associated with an input terminal for receiving the input signal. The input terminal is coupled to the gate of the input MOS transistor. The protection circuit also includes a circuit element for limiting or suppressing the input signal potential at the variable threshold. The gate of the input MOS transistor receives the potential limited signal from the circuit element. The circuit element is responsive to a given threshold control potential. The variable threshold is enhanced by the given threshold control potential when a high-voltage input signal is applied to the input terminal.
