Part Number: SN65HVD75

Hi team,

In below circut, is it possible to remove the pull down resistor (10kohm)?

If not, can you please give some explaation about what will be the expected problem?

Thanks,

    Sam,

    The 1-kΩ to 10-kΩ pullup or pulldown resistors for enable lines are there to limit noise currents in these lines during
    transient events. You can remove them from the system, but you may be more susceptible to noise randomly toggling the enables.
