__________Applic ations Information
The MAX3480A/MAX3480B are designed for bidirection-
al data communications on multipoint bus-transmission
lines. Figure 9 shows a typical network application cir-
cuit. To minimize reflections, terminate the line at both
ends with its characteristic impedance, and keep stub
lengths off the main line as short as possible. The slew-
rate-limited MAX3480B is more tolerant of imperfect ter-
mination and stubs off the main line.
The MAX3480A/MAX3480B are specified and charac-
terized using the resistor values shown in Table 1 of
Figure 2. Altering the recommended values can
degrade performance.
The DI and DE inputs are the cathodes of LEDs whose
anodes are connected to V
CC
. These points are best
driven by a 3.3V CMOS-logic gate with a series resis-
tor to limit the current. The resistor values shown in
Table 1 are recommended when the 74HC240 gate or
equivalent is used. These values may need to be
adjusted if a driving gate with dissimilar series resis-
tance is used. DI and DE are intended to be driven
through a series current-limiting resistor. Directly
grounding these pins destroys the device.
