*1. OUT output presumed to reach reference value 100μs after output enable.

*2.An output voltage error may occur if the output hold time does not satisfy rated value.

*3. Design value, provided as a guide for the output control time.

*4. Design value, representing the capacitance per terminal. Provided as a guide for when designing circuit boards.
