Renesas Electronics Corporation ±10kV ESD Protected, +125°C, 40Mbps, 5V, Full-Duplex, Full Fail-Safe RS-485/RS-422 Transceiver ISL3160EFBZ-T

The ISL3160E is a ±10kV IEC61000 ESD protected, 5V powered, full-duplex transceiver that meets both the RS-485 and RS-422 standards for balanced communication. It also features a large differential output voltage and high data rate (up to 40Mbps) and is offered in the standard industrial (-40°C to +85°C) and extended industrial (-40°C to +125°C) temperature ranges. 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 ±10% tolerance supply, and delivers at least a 2.1V differential output voltage over this supply range. This translates into better noise immunity (data integrity), longer reach, or the ability to drive up to six 120O terminations in “star” or other nonstandard bus topologies at the exceptional 40Mbps data rate.
SCSI applications benefit from the ISL3160E’s low receiver and transmitter part-to-part skews. The ISL3160E 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 at V_OL = 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.
