Looking to buy a photoelectric conversion device: the device is required to output a voltage (or current) signal proportional to the light flux. This signal can be recognized by a common single-chip m...
Due to a design error, two 74HC14 inverters were connected in parallel. I saw relevant information that 74HC14 is a CMOS device with push-pull output, so it should not be used in parallel. Although I ...
