Information

The ISL31475E is a fault protected, extended common mode range differential transceivers that exceed the RS-485 and RS-422 standards for balanced communication. The RS-485 bus pins (driver outputs and receiver inputs) are protected against overvoltages up to ±60V. Additionally, these transceivers operate in environments with common mode voltages up to ±15V (exceeds the RS-485 requirement), making this RS-485 family one of the more robust on the market. Transmitters deliver an exceptional 2.5V (typical) differential output voltage into the RS-485 specified 54Ω load. This yields better noise immunity than standard RS-485 ICs, or allows up to six 120Ω terminations in star topologies. Receiver (Rx) inputs feature a “Full Fail-Safe” design which ensures a logic high Rx output if Rx inputs are floating, shorted, or on a terminated but undriven (idle) bus. Rx outputs feature high drive levels - typically 15mA @ VOL = 1V (to ease the design of opto-coupled isolated interfaces).

Key Features

  • Fault Protected RS-485 Bus Pins = up to ±60V
  • Extended Common Mode Range = ±15V Larger Than Required for RS-485
  • 1/4 Unit Load for up to 128 Devices on the Bus
  • High Transient Over Voltage Tolerance = ±80V
  • Full Fail-safe (Open, Short, Terminated) RS-485 Receivers
  • High Rx IOL for Opto-Couplers in Isolated Designs
  • Hot Plug Circuitry - Tx and Rx Outputs Remain Three-State During Power-up/Power-down
  • Choice of RS-485 Data Rates = 250kbps to 15Mbps
  • Low Quiescent Supply Current = 2.3mA Ultra Low Shutdown Supply Current = 10µA
  • Pb-Free (RoHS Compliant)
