DATASHEET ISL3259E FN6587 Rev.2.00 15kV ESD Protected, 100Mbps, 5V, PROFIBUS, Full Fail-Safe, RS-485/RS-422 Aug 31, 2017 Transceiver The ISL3259E is a 15kV IEC61000 ESD Protected, 5V Features powered, single transceiver that meets both the RS-485 and IEC61000 ESD protection on RS-485 I/O pins 15kV RS-422 standards for balanced communication. It also features the larger output voltage and higher data rate (up to - Class 3 HBM ESD level on all other pins . >9kV 100Mbps) required by high speed PROFIBUS applications. The Large differential V . 2.8V into 54 OUT low bus currents (+220A/-150A) present a 1/5 unit load to Better noise immunity, or drive up to 6 terminations the RS-485 bus. This allows up to 160 transceivers on the Very high data rate up to 100Mbps network without violating the RS-485 specifications load limit, and without using repeaters. 11/13ns (maximum) Tx/Rx propagation delays 1.5ns (maximum) skew This transceiver requires a 5V supply, and delivers at least a 2.1V 1/5 unit load allows up to 160 devices on the bus differential output voltage. This translates into better noise immunity (data integrity), longer reach, or the ability to drive up to Full fail-safe (open, shorted, terminated/undriven) receiver six 120 terminations in star or other non-standard bus High Rx I to drive opto-couplers for isolated applications OL topologies. Hot plug - Tx and Rx outputs remain three-state during SCSI applications benefit from the ISL3259Es low receiver power-up and transmitter part-to-part skews. The ISL3259E is perfect for Low quiescent supply current 4mA high speed parallel applications requiring simultaneous capture of large numbers of bits. The low bit-to-bit skew eases Low current shutdown mode . 1A the timing constraints on the data latching signal. -7V to +12V common mode input voltage range Receiver (Rx) inputs feature a Full Fail-Safe design, which Three-State Rx and Tx outputs ensures a logic high Rx output if Rx inputs are floating, Operates from a single +5V supply shorted, or terminated but undriven. Rx outputs feature high drive levels (typically >30mA V = 1V) to ease the design of Current limiting and thermal shutdown for driver overload OL optically isolated interfaces. protection Pb-free (RoHS compliant) Hot plug circuitry ensures that the Tx and Rx outputs remain in a high impedance state while the power supply stabilizes. Applications Driver (Tx) outputs are short-circuit protected, even for voltages PROFIBUS DP and FMS networks exceeding the power supply voltage. Additionally, on-chip thermal shutdown circuitry disables the Tx outputs to prevent SCSI fast 40 drivers and receivers damage if power dissipation becomes excessive.
