The ISL315xE family of 5V powered RS-485/RS-422 transceivers features high output drive and high ESD protection. The devices 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 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.

特性

  • 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
  • High transient overvoltage tolerance of ±100V
  • Full fail-safe outputs for open or shorted inputs
