±60V Fault Protected, 3.3V to 5V, ±20V Common-Mode Range, RS-485/RS-422

Transceivers with Cable Invert and ±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 ±60V, and against ±15kV ESD strikes.

These transceivers operate in environments with common-

mode voltages up to ±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 V

≥

4.5V and

deliver a 1.1V differential output voltage into the RS-485

specified 54Ω load even with V

= 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).

The ISL32457E and ISL32459E include a cable invert function

that reverses the polarity of the Rx and Tx bus pins in case the

cable is misconnected during installation.

See

Table 1 on page 2

device number.
