Aug 31, 2017 В±60V Fault Protected, 3.3V to 5V, В±20V Common-Mode Range, RS-485/RS-422
Transceivers with Cable Invert and В±15kV ESD
The ISL3245xE are 3.3V to 5V powered, fault protected,
extended Common-Mode Range (CMR) differential
transceivers for balanced communication. The RS-485 bus
pins (driver outputs and receiver inputs) are protected against
overvoltages up to В±60V, and against В±15kV ESD strikes.
These transceivers operate in environments with commonmode voltages up to В±20V (exceeds the RS-485 requirement),
making this RS-485 family one of the more robust on the
market.
Transmitters are RS-485 compliant with VCC ≥ 4.5V and
deliver a 1.1V differential output voltage into the RS-485
specified 54О© load even with VCC = 3V. 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 full fail-safe operation is maintained even
when the Rx input polarity is switched (cable invert function on
ISL32457E and ISL32459E). Features Fault protected RS-485 bus pins up to В±60V Extended common-mode range В±20V
