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. Devices are ESD sensitive. Handling precautions recommended.
Note4. It is highly recommended to solder the exposed pad of the EPAD-TQFP package to a ground plane on the PCB for maximum thermal
efficiency.
Note 5. Outputsloadedwith50-to-ground.
