Rev.3.00
Aug 28, 2017 В±15kV ESD Protected, +125В°C, 40Mbps, 5V, PROFIBUS, Full Fail-safe
RS-485/RS-422 Transceiver
The ISL3159E is a В±15kV IEC61000 ESD protected, 5V
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 (-40В°C to
+125В°C) temperature ranges. The low bus currents
(+220ВµA/-150ВµA) present a 1/5 unit load to the RS-485 bus.
This allows up to 160 transceivers on the network without
violating the RS-485 specification’s load limit and without
using repeaters. Features This transceiver requires a 5V В±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 120О©
terminations in “star” or other nonstandard bus topologies, at
the exceptional 40Mbps data rate. 1/5 unit load allows up to 160 devices on the bus SCSI applications benefit from the ISL3159E’s low receiver
and transmitter part-to-part skews. The ISL3159E is perfect for
high speed parallel applications requiring simultaneous …
