DATASHEET ISL3159E FN6364 Rev.3.00 15kV ESD Protected, +125C, 40Mbps, 5V, PROFIBUS, Full Fail-Safe, Aug 28, 2017 RS-485/RS-422 Transceiver The ISL3159E 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 - Class 3 HBM ESD level on all other pins . >9kV features the larger output voltage and higher data rate (up to 40Mbps) required by high speed PROFIBUS applications, and Large differential V . 2.8V into 54 OUT is offered in industrial and extended Industrial (-40C to Better noise immunity, or drive up to 6 terminations +125C) temperature ranges. The low bus currents High data rates up to 40Mbps (+220A/-150A) present a 1/5 unit load to the RS-485 bus. Specified for +125C operation This allows up to 160 transceivers on the network without violating the RS-485 specifications load limit and without 11/13ns (maximum) Tx/Rx propagation delays 1.5ns using repeaters. (maximum) skew 1/5 unit load allows up to 160 devices on the bus This transceiver requires a 5V 10% tolerance supply, and delivers at least a 2.1V differential output voltage over this Full fail-safe (open, shorted, terminated/undriven) receiver supply range. This translates into better noise immunity (data High Rx I to drive optocouplers for isolated applications OL integrity), longer reach, or the ability to drive up to six 120 Hot plug - Tx and Rx outputs remain three-state during terminations in star or other nonstandard bus topologies, at power-up the exceptional 40Mbps data rate. Low quiescent supply current 4mA SCSI applications benefit from the ISL3159Es low receiver Low current shutdown mode . 1A and transmitter part-to-part skews. The ISL3159E is perfect for -7V to +12V common-mode input voltage range high speed parallel applications requiring simultaneous capture of large numbers of bits. The low bit-to-bit skew eases Three-state Rx and Tx outputs the timing constraints on the data latching signal. Operates from a single +5V supply (10% tolerance) Receiver (Rx) inputs feature a full fail-safe design, which Current limiting and thermal shutdown for driver overload ensures a logic high Rx output if Rx inputs are floating, protection shorted, or terminated but undriven. Rx outputs feature high Pb-free (RoHS compliant) drive levels (typically >30mA at V = 1V) to ease the design of OL optically isolated interfaces. Applications Hot plug circuitry ensures that the Tx and Rx outputs remain in PROFIBUS DP and FMS networks a high impedance state while the power supply stabilizes. SCSI fast 40 drivers and receivers Driver (Tx) outputs are short-circuit protected, even for voltages Motor controller/position encoder systems exceeding the power supply voltage. Additionally, on-chip Factory automation thermal shutdown circuitry disables the Tx outputs to prevent Field bus networks damage if power dissipation becomes excessive.
