1. Over-temperature limits are guaranteed by design and not production tested. Devices tested at +25ºC.
2. Guaranteed by design and not production tested.
Note:
All limits are guaranteed. The parameters with min and max values are guaranteed with production tests or SQC (Statistical Quality
Control) methods.
