driver enables multiple R/B# outputs to be OR-tied. Typically, R/B# is connected to an
interrupt pin on the system controller.
The combination of Rp and capacitive loading of the R/B# circuit determines the rise
time of the R/B# signal. The actual value used for Rp depends on the system timing re-
quirements. Large values of Rp cause R/B# to be delayed significantly. Between the 10%
and 90% points on the R/B# waveform, the rise time is approximately two time con-
stants (TC).
Where R = Rp (resistance of pull-up resistor), and C = total capacitive load.
The fall time of the R/B# signal is determined mainly by the output impedance of the
R/B# signal and the total load capacitance. Approximate Rp values using a circuit load
of 100pF are provided in Figure 21 (page 27).
The minimum value for Rp is determined by the output drive capability of the R/B#
signal, the output voltage swing, and V
