Intersil’s ISL3259E is a ±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
100Mbps) required by high speed PROFIBUS applications.
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 supply, and delivers at least a
2.1V differential output voltage. 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.
