Ready/Busy Signal Electrical Characteristics
Figures 37, 36 and 38 show the electrical charac-
teristics for the Ready/Busy signal. The value re-
quired for the resistor RP can be calculated using
the following equation:
So,
where IL is the sum of the input currents of all the
devices tied to the Ready/Busy signal. RP max is
determined by the maximum value of tr.
