摘要:
An integrated circuit device formed on a chip includes a pair of signal input terminals, a signal discriminating circuit having a pair of input terminals coupled to the signal input terminals, for comparing a data signal and a reference signal supplied through the input terminals and for determining whether or not the level of said data signal is higher than that of said reference signal, a pair of test signal terminals to which a predetermined voltage is applied, and a voltage dividing circuit for dividing the predetermined voltage to thereby generate a test signal to be supplied to the signal discriminating circuit through the input terminals.
