NOTE:

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 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 maximum specification.
