Illustrative Applications
Isolated RS-485 and RS-422 Receivers Using IL610s
IL610s can be used as simple isolated RS-485 or RS-422 receivers, terminating signals at the
IL610 for a fraction of the cost of an isolated node. Cabling is greatly simplified by
eliminating the need to power the input side of the receiving board. No current-limiting
resistor is needed for a single receiver because it will draw less current than the driver
maximum. Current limiting resistors allow at least eight nodes without exceeding the
maximum load of the transceiver chip. Placement of the current-limiting resistors on both
lines provides better dynamic signal balance. There is generally no need for line termination
resistors below data rates of approximately 10 Mbps because the IL610 coil resistance of
approximately 85 Ω is close to the characteristic impedance of most cables. The circuit is
intrinsically open circuit failsafe because the IL610 is guaranteed to switch to the high state
when the coil input current is less than 500 µA.
