Absolute maximum ratings apply individually only, not in

combination. Unless otherwise specified, all other voltages are

referenced to PGND.

THERMAL RESISTANCE

θJA is specified for the worst-case conditions, that is, a device

soldered in a circuit board for surface-mount packages.

Boundary Condition

In determining the values given in Table 2 and Table 3, natural

convection is used to transfer heat to a 4-layer evaluation board.

ESD CAUTION

Stresses a bove 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.
