Features
RAA788153, RAA788155, RAA788156, RAA788158) ▪ High V of 5V powered RS-485 transceivers features high OD: 3.1V (Typ) into RD = 54Ω output drive and high EFT and ESD protection. ▪ ±5kV EFT immunity of bus I/O pins ▪ ±16.5kV ESD protection on bus I/O pins The devices are immune to ±5kV IEC61000-4-4 EFT transients and withstand ±16.5kV IEC61000-4-2 ESD ▪ Supported data rates: 115kbps, 1Mbps, 20Mbps strikes without latch-up. ▪ Full fail-safe outputs for open or shorted inputs The large output voltage of 3.1V typical into a 54Ω ▪ Hot plug capability load provides high noise immunity, and it enables the ▪ 1/8 Unit Load drive of up to 8000ft long bus segments or eight 120Ω ▪ Allows for up to 512 transceivers on the bus terminations in a star topology. ▪ Low supply current (driver disabled): 550µA These devices possess less than 125µA bus input ▪ Ultra-low shutdown current: 70nA currents, therefore, constituting a true 1/8 unit load. The high output drive combined with the low bus input
Applications
currents allows for the connection of up to 512 ▪ Industrial networks in factory automation transceivers on the same bus. ▪ Building automation: lighting, elevators, HVAC The receiver inputs feature a full fail-safe design that ▪ Industrial process control networks turns the receiver outputs high when the bus inputs are open or shorted. ▪ Security camera networks ▪ Networks with star topology The RAA78815x family includes half and full-duplex transceivers with active-high driver-enable pins and ▪ Long-haul networks in coal mines and oil rigs active-low receiver enable pins. These transceivers ▪ High node-count networks support data rates of 115kbps, 1Mbps, and 20Mbps ▪ Automated utility e-meter reading systems with a performance that is characterized from -40°C to +85°C.
