Note 1: Install the device correctly. Otherwise, the device or system may be degraded, damaged or even destroyed.
Note 2: The protection features are intended to avoid output short-circuits or other abnormal conditions temporarily.
It is not guaranteed that they will prevent the IC from being damaged.
Exposure to conditions beyond the guaranteed operating ranges may not activate the protection features,
resulting in an IC damage due to output short-circuits.
Note 3: If HBM ESD(condition; 100pF/1.5k
Ω
) of under -1900V is applied to pin 2 or pin 4 in case that pin3 is GND,
this product may break down.
