Ready/Busy Signal Electrical Characteristics
Figures
35
,
34
and
36
show the electrical charac-
teristics for the Ready/Busy signal. The value re-
quired for the resistor R
P
can be calculated using
the following equation:
So,
where I
L
is the sum of the input currents of all the
devices tied to the Ready/Busy signal. R
P
max is
determined by the maximum value of t
r
.
