DATASHEET ISL3179E, ISL3180E FN6365 Rev. 6.00 High ESD Protected, +125C, 40Mbps, 3.3V, Full Fail-Safe RS-485/RS-422 Nov 9, 2017 Transceivers The ISL3179E and ISL3180E are high ESD protected (see Features Table 2 on page 2), 3.3V powered, single transceivers that High ESD protection on RS-485 I/O pins meet both the RS-485 and RS-422 standards for balanced communication. Each device has low bus currents - ISL3179E . 16.5kV IEC61000 (+220A/-150A), so they present a 1/5 unit load to the - ISL3180E 12kV HBM RS-485 bus. This allows up to 160 transceivers on the network - Class 3 HBM level on all other pins (ISL3179E) . >9kV without violating the RS-485 specifications 32 unit load Specified for +125C operation maximum, and without using repeaters. High data rates . up to 40Mbps Receiver (Rx) inputs feature a full fail-safe design, which ensures a logic high Rx output if Rx inputs are floating, 5V tolerant logic inputs shorted, or terminated but undriven. 1/5 unit load allows up to 160 devices on the bus The ISL3180E is configured for full duplex applications. The Full fail-safe (open, shorted, terminated/undriven) receiver ISL3179E half duplex version multiplexes the Rx inputs and Tx Hot plug - Tx and Rx outputs remain three-state during outputs to allow a transceiver with an output disable function power-up in 8 Ld packages. Low quiescent current . 4mA (max) Hot plug circuitry ensures that the Tx and Rx outputs remain in Low current shutdown mode . 1A (max) a high impedance state while the power supply stabilizes. -7V to +12V common-mode input voltage range Related Literature Three-state Rx and Tx outputs For a full list of related documents, visit our website 16/16.5ns (max) Tx/Rx propagation delays 1.5ns (max) skew - ISL3179E and ISL3180E product pages Operates from a single +3.3V supply (10% tolerance) Current limiting and thermal shutdown for driver overload Applications protection Motor controller/position encoder systems Pb-free (RoHS compliant) Factory automation TABLE 1.
