RAA788150, RAA788152, RAA788153, RAA788155, RAA788156, RAA788158 Large 3V Output Swing, 5kV EFT, 16.5kV ESD, RS-485 Transceivers
2023-05-29
●The RAA78815x family (RAA788150, RAA788152, RAA788153, RAA788155, RAA788156, RAA788158) of 5V powered RS-485 transceivers features high output drive and high EFT and ESD protection.
●The devices are immune to ±5kV IEC61000-4-4 EFT transients and withstand ±16.5kV IEC61000-4-2 ESD strikes without latch-up.
●The large output voltage of 3.1V typical into a 54Ω load provides high noise immunity, and it enables the drive of up to 8000ft long bus segments or eight 120Ω terminations in a star topology.
●These devices possess less than 125μA bus input currents, therefore, constituting a true 1/8 unit load. The high output drive combined with the low bus input currents allows for the connection of up to 512 transceivers on the same bus.
●The receiver inputs feature a full fail-safe design that turns the receiver outputs high when the bus inputs are open or shorted.
●The RAA78815x family includes half and full-duplex transceivers with active-high driver-enable pins and active-low receiver enable pins. These transceivers support data rates of 115kbps, 1Mbps, and 20Mbps with a performance that is characterized from -40°C to +85°C.
