Single Transmitter/Receiver RS-422/RS-485 8-Pin SOIC N
Manufacturer Part #: ISL31475EIBZ
Alternate Part #: ISL31475EIBZ
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).
