DATASHEET ISL3150E, ISL3152E, ISL3153E, ISL3155E, ISL3156E, ISL3158E FN6363 Large 3V Output Swing, 16.5kV ESD, Full Fail-Safe, 1/8 Unit Load, Rev.5.1 May 11, 2021 RS-485/RS-422 Transceivers The ISL315xE (ISL3150E, ISL3152E, ISL3153E, Features ISL3155E, ISL3156E, and ISL3158E) family of 5V High V : 3.1V (Typ) into R = 54 OD D powered RS-485/RS-422 transceivers features high Low bus currents: 125A constitutes a true 1/8 unit output drive and high ESD protection. The devices load withstand 16.5kV IEC61000-4-2 ESD strikes without latch-up. The large output voltage of 3.1V typical into a Allows for up to 512 transceivers on the bus 54 load provides high noise immunity, and enables the 16.5kV ESD protection on bus I/O pins drive of up to 8000ft long bus segments, or eight 120 terminations in a star topology. High transient overvoltage tolerance of 100V These devices possess less than 125A bus input Full fail-safe outputs for open or shorted inputs currents, thus constituting a true 1/8 unit load. The high Hot plug capability - driver and receiver outputs output drive combined with the low bus input currents remain high-impedance during power-up and allows for connecting up to 512 transceivers on the same power-down bus. Supported data rates: 115kbps, 1Mbps, 20Mbps The receiver inputs feature a full fail-safe design that Low supply current (driver disabled): 550A turns the receiver outputs high when the bus inputs are open or shorted. Ultra-low shutdown current: 70nA The ISL315xE family includes half and full-duplex Applications transceivers with active-high driver-enable pins and Automated utility e-meter reading systems active-low receiver enable pins. These transceivers support data rates of 115kbps, 1Mbps, and 20Mbps. High node count systems Their performance is characterized from -40C to +85C.
