Parameter

Limits1

1. For normal device operation, adhere to the limits in this table. Sustained

operation of a device at conditions exceeding these values, even if they are

within the absolute maximum rating limits, can result in permanent device

damage or impaired device reliability. Device functionality to stated DC and

AC limits is not guaranteed if recommended operating conditions are

exceeded.
