ISL3259E

DATASHEET ISL3259E ±15kV ESD Protected, 100Mbps, 5V, PROFIBUS, Full Fail-Safe, RS-485/RS-422 Transceiver FN6587 Rev.2.00 Aug 31, 2017 The 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. This allows 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. SCSI applications benefit from the ISL3259E’s low receiver and transmitter part-t...
