Application Information
Device Connection for Protection of RS-485
Interfaces
EIA RS-485 species a ±7V ground dierence between
devices on the bus. This permits the bus voltage to
range from +12V (5V + 7V) to -7V (0 - 7V).
Because of this requirement, each TClamp1202P can
be congured to protect one line for common mode
surges or one line pair for dierential surges.
The example below illustrates how to connect the
TClamp1202P for common mode and dierential
mode protection on an RS-485 interface. For common
mode protection, one of the TClamp1202P data pins
(pin 1 or 3) is connected to the TX/RX line and the
other is connected to ground. Pins 4 and 5 as well as
the center tab are not connected. This eectively
makes the device look like a bidirectional 12V TVS to
the circuit. For dierential mode protection, each of
the device data pins (1 and 3) are connected to the
transceiver RX/TX pins as shown. Again, Pins 4, 5 and
the center tab are not connected.
