The times are specified without leakage current. For a leakage current of 10 A on the SVR pin, the delta time is specified. If the
capacitor value on the SVR pin changes with 30 %, the specified time will also change with 30 %. The specified times include an
Equivalent Series Resistance (ESR) of 15

the maximal LOW level is defined by V
For optimum channel separation, supply voltage ripple rejection and common mode rejection ratio, a resistor
be in series with the ACGND capacitor.
