Renesas Electronics ISL3245xE RS-485/RS-422 Transceivers

Renesas Electronics ISL3245xE RS-485/RS-422 Transceivers are ±60V fault protected, 3.3V to 5V powered, ±20V common-mode range differential transceivers for balanced communication. The extended common-mode range is larger than required for the RS-485. Renesas Electronics RS-485 are protected against overvoltages up to ±60V and against ±15kV ESD strikes. These transceivers operate in environments with common-mode voltages up to ±20V.

Features

  • Up to ±60V fault protected RS-485 bus pins
  • ±20V larger than required for RS-485 common-mode range
  • ±15kV HBM ESD protection on RS-485 bus pins
  • 3V to 5.5V wide supply range
  • Cable invert pin (ISL32457E and ISL32459E only) corrects for reversed cable connections while maintaining Rx full fail-safe functionality
  • 1/4 unit load for up to 128 devices on the bus
  • ±80V high transient overvoltage tolerance
  • Full fail-safe (open, short, terminated) RS-485 receivers
  • Up to 20Mbps data rates
  • 2.1mA low quiescent supply current

Applications

  • Utility meters/automated meter reading systems
  • Air conditioning systems
  • Security camera networks
  • Building lighting and environmental control systems
  • Industrial/process control networks
