Integrated circuit having an input voltage-clamping function and an input current-detecting function |
摘要 |
An integrated circuit has an input voltage-clamping function and an input current-detecting function. A voltage-clamping circuit is provided for clamping a voltage at the input signal terminal, the voltage being clamped in response to an input current greater than a first predetermined value supplied to the input terminal. A current detecting circuit is also provided for detecting whether the input current supplied to the input terminal is greater than a second predetermined value, whereby the single input terminal for signals is used for both functions, i.e., the input voltage-clamping function and the input current-detecting function.
