More Information
Summary:Herein disclosed is a digital semiconductor integrated circuit which is equipped with: a digital signal input circuit; an analog signal input circuit made receptive of an analog signal for feeding out a digital signal corresponding to said analog signal; and a common external terminal connected commonly with the input terminals of said digital signal input circuit and said analog signal input circuit. By the preparation with the use of a suitable switch circuit, the common external terminal can be used as either an analog signal input terminal or a digital signal input terminal. As a result, the number of the external output terminals required for the semiconductor integrated circuit can be reduced.
