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
in series with 100pF. Machine model, 0 in series with 200pF.
