ISL3155EIBZ

ISL3155EIBZ is a large 3V output swing, full fail-safe, 1/8 unit load, RS-485/RS-422 transceiver. The receiver inputs feature a full fail-safe design that turns the receiver's outputs high when the bus inputs are open or shorted. Typical applications include automated utility e-meter reading systems, high node count systems, PROFIBUS and Fieldbus systems in factory automation, security camera networks, lighting, elevator, and HVAC control systems in building automation, industrial process control networks, networks with star topology, long-haul networks in coal mines and oil rigs.

• High VOD: 3.1V (typ) into RD=54ohm
• Allows for up to 512 transceivers on the bus
• High transient overvoltage tolerance of ±100V
• Full fail-safe outputs for open or shorted inputs
• Hot plug capability: driver and receiver's outputs remain high-impedance during power-up/power-down
• No-load supply current is 550µA typ at DE=0V, RE=0V, VCC=5V, TA=+25°C
• Shutdown supply current is 0.07µA typ at DE=0V, RE=VCC, DI=0V or VCC, VCC=5V, TA=+25°C
• Half duplex, 1Mbps data rate, 150ns rise/fall time
• 3/4ns Tx/Rx skew, ±16kV bus ESD
• 8 Ld SOIC package, -40 to +85°C temperature range
