(1) 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 under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Operation above 4.8V input voltage for extended periods may affect device reliability.
(3) All voltage values are with respect to network ground terminal.
(4) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may
have to be derated. Maximum ambient temperature (T
A(max)
) is dependent on the maximum operating temperature (T
INT(max)
), the
maximum power dissipation of the device in the application (P
D(max)
), and the junction-to-ambient thermal resistance of the part/package
in the application (θ
JA
), as given by the following equation: T
A(max)
= T
J(max)
–(θ
JA
X P
D(max)
). To achieve optimum performance, it is
recommended to operate the device with a maximum internal temperature of 105°C.
(5) The human body model is a 100-pF capacitor discharged through a 1.5-kΩ resistor into each pin. The machine model is a 200-pF
capacitor discharged directly into each pin.
