BOUNDARY CONDITION
In determining the values given in Table 2 and Table 3, natural
convection was used to transfer heat to a 4-layer evaluation board.
ESD CAUTION
Temperature (10 sec)
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
Absolute maximum ratings apply individually only, not in
combination. Unless otherwise specified, all other voltages are
referenced to PGND.
