cabling can be as long as 4,000 feet, RS-485
transceivers are equipped with a wide (-7V to
+12V) common mode range to accomodate
ground potential differences. Because the
RS-485 protocol is a differential interface, data
is virtually immune to noise in the transmission
line.
Receiver...
The
SP3488
and the
SP3489
receivers have
differential inputs with an input sensitivity
as low as +100mV. Input impedance of the
receivers is typically 15K
(12K
minimum).
A wide common mode range of -7V to +12V
allows for large ground potential differences
between systems.
The
SP3488
features active HIGH and active
LOW common receiver enable controls. Refer
to
SP3488
Truth Table in
Table 1
. The
SP3489
provides independent, active high receiver
enable controls for each pair of receivers. Refer
to
SP3489
Truth Table in
Table 2
. Both devices
feature tri-state outputs and a -7V to +12V
common-mode input range permitting a +7V
ground difference between devices on the
communication bus. The
SP3488
and the
SP3489
are equipped with a fail-safe feature which forces
a logic HIGH at the receiver output when the
input is left floating. The
SP3488
and
SP3489
receivers meet the electrical specifications of
RS-485 and RS-422 serial protocol data rates up
to 10Mbps under load.
