NOTE: 1 When using open collector parts, the value of the pull-up resistor greatly affects the value of the tPLH. For example, changing the specified pull-up resistor value from 500 to 100 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.
