Claim 3:
4. The device of claim 3, wherein
the first protection circuit further comprises
a second buffer circuit connected between the first pad and the second pad on the output side of the voltage detection circuit and on an input side of the discharge element and configured to invert a logic of the discharge instruction signal and amplify the discharge instruction signal,
a third noise filter circuit connected to an output side of the second buffer circuit and the input side of the discharge element and configured to suppress an error of an output signal of the second buffer circuit due to the power supply noise, and
a third buffer circuit connected between the first pad and the second pad on an output side of the third noise filter circuit and on the input side of the discharge element and configured to invert a logic of an output signal of the third noise filter circuit and amplify the output signal of the third noise filter circuit, and
the discharge circuit further includes a sixth buffer circuit connected between the third pad and the fourth pad on the output side of the third noise filter circuit and on an input side of the second discharge element and configured to invert the logic of the output signal of the third noise filter circuit and amplify the output signal of the third noise filter circuit.
