DC ELECTRICAL CHARACTERISTICS

Note 1.

Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied

at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratlng conditions for extended

periods may affect device reliability.

Note 2.

The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.

Note 3.

It is recommended that the user always solder the exposed die pad to a ground plane for enhanced heat dissipation.

Note 4.

CCA, VCC_LOGIC, VCCOA/C are not internally connected together inside the device. They must be connected together on the PCB. VCCOB is a

separate supply.

Note 5.

No load. Outputs floating, Banks A, B, and C enabled.
