Abstract
A discharge control circuit is connected between an output signal line of a boot-strap circuit having an allowable output signal voltage level range and a low voltage line. If an output signal voltage level of the output signal line is within the allowable output signal voltage level range, then the discharge control circuit provides no electrical connection between the output signal line and the low voltage line and if the output signal voltage level of the output signal line exceeds the allowable output signal voltage level range, then the discharge control circuit provides an electrical connection between the output signal line and the low voltage line.
