摘要:
A BiCMOS auxiliary output driver is provided to maintain output logic signal levels when integrated circuit chip power supply voltage is outside its nominal range. When the power supply voltage level is within design tolerance for a MOSFET output driver stage, the auxiliary output driver is off; when below design tolerance, the auxiliary output driver is turned on. Driver stage output pad signal level is maintained at a desired state level by the auxiliary output driver whenever the power supply slips below its design tolerance range.
