Note:	Output characteristics are the values of the applied circuit conditions, below. Also, the microcomputer input terminals actually used use the following voltages. Low level input terminal: 1.5 V or less High level input terminal: 3.5 V or higher Please use with a detection method to prevent malfunction. Refer to the “Preventing a malfunction” of “CAUTIONS FOR USE”.
