RS-485/RS-422 Transceivers
Intersil’s ISL3159E is a
powered, single transceiver that meets both the RS-485 and
RS-422 standards for balanced communication. It also
features the larger output voltage and higher data rate - up to
40Mbps - required by high speed PROFIBUS applications,
and is offered in Industrial and Extended Industrial (-40°C to
+125°C) temperature ranges. The low bus currents
(+220μA/-150μA) present a “1/5 unit load” to the RS-485 bus,
thus allowing up to 160 transceivers on the network without
violating the RS-485 specification’s load limit, and without
using repeaters.
This transceiver requires a 5V ±10% tolerance supply, and
delivers at least a 2.1V differential output voltage over this
supply range. This translates into better noise immunity
(data integrity), longer reach, or the ability to drive up to six
120Ω terminations in “star” or other non-standard bus
topologies, at the exceptional 40Mbps data rate.
SCSI applications benefit from the ISL3159’s low receiver
and transmitter part-to-part skews, which make it perfect for
high speed parallel applications where large numbers of bits
must be simultaneously captured. The low bit-to-bit skew
eases the timing constraints on the data latching signal.
Receiver (Rx) inputs feature a “Full Fail-Safe” design, which
ensures a logic high Rx output if Rx inputs are floating,
shorted, or terminated but undriven. Rx outputs feature high
drive levels (typically >30mA @ V
of optically isolated interfaces.
Hot Plug circuitry ensures that the Tx and Rx outputs remain
in a high impedance state while the power supply stabilizes.
Driver (Tx) outputs are short circuit protected, even for
voltages exceeding the power supply voltage. Additionally,
on-chip thermal shutdown circuitry disables the Tx outputs to
prevent damage if power dissipation becomes excessive.

Application Information RS-485 and RS-422 are differential (balanced) data transmission standards for use in long haul or noisy environments. RS-422 is a subset of RS-485, so RS-485 transceivers are also RS-422 compliant. RS-422 is a point-to-multipoint (multidrop) standard, which allows ...
