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 120O terminations in “star” or other non-standard bus topologies.
SCSI applications benefit from the ISL3259E’s low receiver and transmitter part-to-part skews. The ISL3259E is perfect for high speed parallel applications requiring simultaneous capture of large numbers of bits. The low bit-to-bit skew eases the timing constraints on the data latching signal.
Receiver (Rx) inputs feature a “Full Fail-Safe” design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or terminated but undriven. Rx outputs feature high drive levels (typically 30mA @ VOL = 1V) to ease the design of optically isolated interfaces.
Hot plug circuitry ensures that the Tx and Rx outputs remain in a high impedance state while the power supply stabilizes.
Driver (Tx) outputs are short-circuit protected, even for voltages exceeding the power supply voltage. Additionally, on-chip thermal shutdown circuitry disables the Tx outputs to prevent damage if power dissipation becomes excessive.
