TYPICAL PROPAGATION DELAYS VERSUS LOAD FOR OPEN COLLECTOR OUTPUTS
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
up to 50% with only a slight increase 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.
