The ISL315xE Series 5V power RS-485/RS-422 transceiver has high output drive and high ESD protection. These transceivers support data rates of 115 KBPS, 1Mbps, and 20Mbps. Its performance ranges from -40°C to +85°C. The device can withstand ±16.5kV IEC61000-4-2 ESD shocks without latching. The typical 3.1V large output voltage to 54Ω loads provides high anti-jamming, and enables drivers to reach 8000ft long bus segments, or eight 120-ω terminals in a star topology.
Typical driver output performance of the ISL315xE transceiver
These devices have bus input currents of less than 125µA and thus constitute a true 1/8 unit load. The combination of high output drivers with low bus input currents allows up to 512 transceivers to be connected on the same bus. The receiver input has a complete fail-safe design that turns the receiver output up when the bus input is open or short-circuited. The ISL315xE family includes half-duplex and full-duplex transceivers with active - high drive enable pins and active - low receiver enable pins.
