__________Applications 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 VCC. 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.
