Abstract

PURPOSE:To prevent 2 signals or more to be selected by connecting gate circuits for controlling plural MOSFETs (MOS field effect transistors), respectively and inhibiting the gate circuits when another selective signal is inputted. CONSTITUTION:When a selective signal is applied only to a terminal 12, an output of an NOR gate is turned to the high level, an MOSFET 28 is turned on and an input signal of a terminal 33 is selected and outputted from an output terminal 38. When a selective signal is inputted both the terminals 12, 13, the outputs of NOR gates 23, 18-21 are turned to the low level and all the MOSFETs 28-32 are turned off. However, the input signals from the terminal 33 are continued to be outputted to the terminal 38 by the capacity of the terminal 38.
