*1.Hysteresis denotes the difference in forward LED current value, expressed in percentage, calculated from the respective forward LED currents when the photo IC in turned from ON to OFF and when the photo IC in turned from OFF to ON.
*2.The value of the response frequency is measured by rotating the disk as shown below.
*3.The following illustrations show the definition of response delay time.
