LM3880, pullup and pulldown resistors

Other Parts Discussed in Thread: LM3880

Hi all,

I've looked into datasheet of LM3880 and found that in a typical application there is pull up resistors in use on output flags. Since I'm using this device with Load Switches, I've two questions:

- When LM3880 is not powered or EN pin is low, I've on output flags logic level 0 even with pullup resistors?

- Since I need to place pull down of 100kohm on EN pin on each Load Switch, what happen with one pull up and one pull down resistor on same signal?

Thank you!
