NOTES:
4. V_LOGIC = Input voltage to perform proper function.
5. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this datasheet.
6. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal voltage range.
7. r_ON matching between channels is calculated by subtracting the channel with the highest max r_ON value from the channel with lowest max r_ON
value, between HSD2 and HSD1 or between FSD2 and FSD1.
