For example, changing the specified pull-up resistor value from 500Ω to 100Ω will improve the tPLH up to 50% with only a slight increase in the tPHL. However, if the value of the pull-up resistor is changed, the user must make certain that the total IOL current through the resistor and the total IIL’s of the receivers does not exceed the IOL minimum specification.
