ABSTRACT:
A semiconductor integrated circuit device for setting operational functions dependent on connection of a first bonding pad (20) to a power supply includes switching transistors (Q11, Q40, Q52, Q32) for resetting an input signal line (30) connected to the first bonding pad to a predetermined potential when there is no power supply potential applied to the first bonding pad immediately after turn-on of an operation power supply, at least one inverter (Q3, Q4, Q13, Q14; Q42, Q43; Q50, Q51) responsive to the turn-on of the power supply for the device, for setting and maintaining the potential on the input signal line, and switching transistors (Q12; Q32; Q41; Q52) to be turned on in response to output of the inverter, for cutting off a current path from the power supply through the bonding pad to the input signal line.
