Notes:
Stresses greater than those listed in Table 7 may cause permanent damage to the
module. This is a stress rating only and functional operation of the module at these or
any other conditions outside those indicated in the device data sheet are not implied.
Exposure to absolute maximum rating conditions for extended periods may adversely
affect reliability.
