(1)

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.

(2)

All voltages are with respect to GND.

(1)

Power ratings are based on the low-k board (1 signal, 1 layer).

(2)

Power ratings are based on the high-k board (2 signal, 2 plane) with PowerPAD™ vias to the internal ground plane.

(3)

Lower ratings are for low-k printed circuit board layout (single -sided). Higher ratings are for enhanced high-k layout, (2 signal, 2 plane)

with a 1mm2 copper pad on pin 2 and 2 vias to the ground plane.

Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account

separately.
