ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(+VS = +3.0V to +5.5V, TA = -55
°C to +125°C, unless otherwise noted. Typical values are at +VS = +3.3V, TA = +25°C.) (Notes 4, 5)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifica-
tions do not apply when operating the device beyond its rated operating conditions.
Note 2: When the input voltage (VI) at any pin exceeds the power supplies (VI < GND or VI > + VS), the current at that pin should be
limited to 5mA. The 20mA maximum package input current rating limits the number of pins that can safely exceed the power
supplies with an input current of 5mA to 4.
Note 3: Human Body Model, 100pF discharged through a 1.5k
Ω resistor.
