stg
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.
NOTES:
1. All voltage values, except differential input/output bus voltage, are with respect to network ground terminal.
2. Maximum power dissipation is a function of TJ(max),
θ
JA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max)
–
TA)/
θ
JA. Operating at the absolute maximum TJ of 150
°
C can affect reliability.
3. The package thermal impedance is calculated in accordance with JESD 51-7.
