Note:
1. TO = 25(Operating Temperature)
2. Do not short-circuit two or more output pins simultaneously.
3. If even one of the above parameters exceeds the absolute maximum ratings even momentarily, the quality of the product may be degraded. The absolute maximum ratings, therefore, specify the value exceeding which the product may be physically damaged. Use the product well within these ratings.
4. The specifications and conditions shown in DC Characteristics and AC characteristics are the ranges for normal operation and quality assurance of the product.
