Abstract

PURPOSE: To provide a title device which is capable of preventing a leakage current from being produced in an I/O cell even in the case voltage is applied to an output terminal of the I/O cell upon an operating power supply being interrupted by providing in the I/O cell a second MOS transistor intervening between a source and a backgate of a driving MOS transistor.
CONSTITUTION: A title semiconductor integrated circuit device comprises a logic cell 35 and an I/O cell for driving a driving MOS transistor 28 in response to an operation result of the logic cell 35 and outputting a digital signal from an output terminal 36, said MOS transistor 28 being adapted such that high potential powersupply VDD is applied to its drain 23 and an operation result of the logic cell 35 is received by a gate 26 to output a digital signal from a source 24 to an output terminal 36. In this device, a second MOS transistor 34 intervening between a source 24 and a backgate of the driving MOS transistor 28 is provided in the I/O cell, which transistor 34 is supplied at its gate 33 with voltage which is switched off when the application of the high potential power supply VDD to the drain 23 of the driving MOS transistor 28 is interrupted.
