OPERATING CONDITIONS (Cont’d)
12.4 LVD/AVD CHARACTERISTICS
12.4.1 Operating Conditions with Low Voltage Detector (LVD)
Subject to general operating conditions for T
Notes:
1. Data based on characterization results, not tested in production.
2. If the medium or low thresholds are selected, the detection may occur outside the specified operating voltage range.
