The recommended operating voltage range is 1.8V to 5.5V, with a typical voltage of 3.3V.
The POR circuitry is internal and does not require any external components. It ensures the device is properly reset during power-up.
The VSS pin is the ground pin and should be connected to the system ground.
The device is rated for operation up to 125°C, but it's recommended to derate the voltage and current according to the temperature derating curve in the datasheet.
Follow proper PCB design and layout guidelines, use a ground plane, and consider adding external filtering components if necessary.
