Abstract
A semiconductor integrated circuit device is provided with an input and/or an output terminal and at least one semiconductor device. The circuit has a resistor provided between the input terminal and/or the output terminal and one of the at least one semiconductor devices and an electronic switch connected in parallel with the resistor. The electronic switch is on-off controlled so as to exhibit a relatively low impedance when the semiconductor device is in operation and a relatively high impedance when the semiconductor device is not in operation. Thus, the semiconductor integrated circuit device is operable at a higher speed with an improved reliability and/or with controllable response characteristics, as compared with the conventional device.
