Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
I
/PBRST has an internal pull-up resistor to V
Guaranteed by design
/PBRST must be held low for a minimum of 20ms to guarantee a reset
V
/RST has an open drain output
