Part Number: SN75LVDS83B


Hi team,

In SN75LVDS83B datasheet of 10 Application and implementation, I saw D0-D27 pull up.

1. May I know if it must pull up? And what about pull down? What is effect?

2. I also saw the Input pin has internal pull down, TYP=100K resistor @ 3.3V. May I know the MIN value of this resistor?

Thanks!

    Hello Eggsy,

    1. The pullups or pulldowns are not needed for proper operation. I believe the schematic just had those for evaluation purposes to manually pull the inputs high or low for test. 

    2. Unfortunately we do not have characterization data for the minimum value - only the typical for this parameter

    Best Regards,
