±15kV ESD, 5V, Full Fail-Safe, 1/8 Unit Load, RS-485/RS-422 Transceivers

The ISL8308xE are BiCMOS, ESD protected, 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Each driver output, and receiver input, is protected against ±15kV ESD strikes without latch-up, and unlike competitive products, this Intersil family is specified for 10 tolerance supplies (4.5V to 5.5V).
