Note: In case of power on, power failure or hot insertion with VDD,VSS present and Vbat floating the Absolute Maximum Ratings can be exceeded
with Vbat > VSS +0.5V. In this case the power consumption of the device increases and the logic output state including relay driver are
not controlled. This effect can be prevented ensuring that Vbat is always present before VDD and VSS or connecting one shottky diode
(e.g. BAT49X or equivalent) between Vbat and VSS. One diode can be shared between all the SLICs of the same line card.
