NOTE:
1
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
PLH
up to 50% with only a slight increase in the t
PHL
. 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
minimum specification.
