Datasheet RAA788150, RAA788152, RAA788153, RAA788155, RAA788156, RAA788158 Large 3V Output Swing, 5kV EFT, 16.5kV ESD, RS-485 Transceivers The RAA78815x family (RAA788150, RAA788152, Features RAA788153, RAA788155, RAA788156, RAA788158) High V : 3.1V (Typ) into R = 54 OD D of 5V powered RS-485 transceivers features high 5kV EFT immunity of bus I/O pins output drive and high EFT and ESD protection. 16.5kV ESD protection on bus I/O pins The devices are immune to 5kV IEC61000-4-4 EFT Supported data rates: 115kbps, 1Mbps, 20Mbps transients and withstand 16.5kV IEC61000-4-2 ESD Full fail-safe outputs for open or shorted inputs strikes without latch-up. Hot plug capability The large output voltage of 3.1V typical into a 54 1/8 Unit Load load provides high noise immunity, and it enables the drive of up to 8000ft long bus segments or eight 120 Allows for up to 512 transceivers on the bus terminations in a star topology. Low supply current (driver disabled): 550A These devices possess less than 125A 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 Security camera networks are open or shorted. Networks with star topology The RAA78815x family includes half and full-duplex Long-haul networks in coal mines and oil rigs transceivers with active-high driver-enable pins and 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 -40C to +85C. 140 3 RAA788158 120 R =20 2 L 100 R =60 R =15 L L 1 80 0 Standard 60 R =120 L Transceiver -1 40 20 -2 20Mbps, 50m UTP, R = 60 0.0 L -3 0 1 234 5 20ns/DIV Driver Output Voltage V (V) OD Figure 1.
