ISL41334

±15kV ESD Protected, 5V, Two Port, Dual Protocol (RS-232/RS-485) Transceivers

Product Status: Mass Production

KEY FEATURES

  • ±15kV (HBM) ESD protected bus pins (RS-232 or RS-485)
  • Two independent ports, each user selectable for RS-232 (2 transceivers) or RS-485, RS-422 (1 transceiver)
  • Single 5V (10% tolerance) supply
  • Flow-through pinouts simplify board layouts
  • Pb-Free (RoHS compliant)
  • Large (2.7V) differential VOUT for improved noise immunity in RS-485, RS-422 networks
  • Full fail-safe (open/short) Rx in RS-485, RS-422 mode
  • Loopback mode facilitates board self-test functions
  • User selectable RS-485 data rates (ISL41334 only)
  • Fast speed: 20Mbps
  • Slew rate limited : 460kbps
  • Slew rate limited: 115kbps
  • Fast RS-232 data rate: up to 650kbps
  • Low current Shutdown mode: 42μA
  • QFN package saves board space (ISL41334 only)
  • Logic supply pin (VL) eases operation in mixed supply systems (ISL41334 only)
