NOTE:
When using Open-Collector parts, the value of the pull–up resistor greatly affects the value of the t
. For example, changing the specified pull-up resistor value from
500
to 100
will improve the t
over 300% with only a slight change in the t
. However, if the value of the pull-up resistor is changed, the user must make certain
that the total I
OL
current through the resistor and the total I
IL
’s of the receivers does not exceed the I
OL
maximum specification.
