Note 1:
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2:
Temperature range specifications is guaranteed by design.
Note 3:
Quiescent current will increase substantially above 5.5 volts, but is very low in the normal range below 5.5 volts.
Note 4:
Human body model, 1.5k
