Large 3V Output Swing, 5kV EFT, 16.5kV ESD, RS-485 Transceivers 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. Features
▪ High VOD: 3.1V (Typ) into RD = 54Ω
▪ ±5kV EFT immunity of bus I/O pins
▪ ±16.5kV ESD protection on bus I/O pins
▪ Supported data rates: 115kbps, 1Mbps, 20Mbps
▪ Full fail-safe outputs for open or shorted inputs 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. ▪ Hot plug capability 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. ▪ Ultra-low shutdown current: 70nA The receiver inputs feature a full fail-safe design that
turns the receiver outputs high when the bus inputs
are open or shorted. ▪ Allows for up to 512 transceivers on the bus …
