†
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 I/O bus voltage, are with respect to network ground terminal.
2. Maximum power dissipation is a function of T
J
(max),
θ
JA
, and T
A
. The maximum allowable power dissipation at any allowable
ambient temperature is P
D
= (T
J
(max) – T
A
)/
θ
JA
. Operating at the absolute maximum T
J
of 150°C can affect reliability.
3. The package thermal impedance is calculated in accordance with JESD 51-7.
