ISL3152E

DATASHEET ISL3150E, ISL3152E, ISL3153E, ISL3155E, ISL3156E, ISL3158E Large 3V Output Swing, 16.5kV ESD, Full Fail-Safe, 1/8 Unit Load, RS-485/RS-422 Transceivers The ISL315xE (ISL3150E, ISL3152E, ISL3153E, ISL3155E, ISL3156E, and ISL3158E) family of 5V powered RS-485/RS-422 transceivers features high output drive and high ESD protection and high EFT immunity. The devices withstand ±16.5kV IEC61000-42 ESD strikes and are immune to ±4kV IEC6100-4-4 EFT transients without latch-up. The large output voltage of 3.1V typical into a 54Ω load provides high noise immunity, and 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, thus constituting a true 1/8 unit load. The high output drive combined with the low bus input currents allows for connecting 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 ISL315xE 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. Their performance is characterized from -40°C to +85°C. Features High VOD: 3.1V (Typ) into RD = 54Ω Low bus currents: 125µA constitutes a true 1/8 unit load Allows for up to 512 transceivers on the bus ±16.5kV ESD protection on bus I/O pins ±4kV EFT immu...
