ISL3156EIUZ-T7A

ISL3156EIUZ-T7A 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
• Full duplex, 20Mbps data rate, 8ns rise/fall time
• 0.2/2.5ns Tx/Rx skew, ±10kV bus ESD
• 10 Ld MSOP package, -40 to +85°C temperature range
