ISL83080E/82E/83E/85E/86E/88E
±15kV ESD, 5V, Full Fail-Safe, 1/8 Unit Load, RS-485/RS-422 Transceivers
The ISL8308xE (ISL83080E, ISL83082E, ISL83083E, ISL83085E, ISL83086E, ISL83088E) 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 family is specified for 10% tolerance supplies (4.5V to 5.5V).
These devices have very low bus currents (+125µA/-75µA), so they present a true 1/8 unit load to the RS-485 bus. This allows up to 256 transceivers on the network without violating the RS-485 specification’s 32 unit load maximum, and without using repeaters.
