ISL317xE RS-422/RS-485 Interface ICs

Renesas Electronics ISL317xE RS-422/RS-485 Interface ICs are 3.3V powered single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. The ISL317xE feature very low bus currents +125µA/-100µA, that present a true “1/8 unit load” to the RS-485 bus. This feature allows up to 256 transceivers on the network without violating the RS-485 specification’s 32 unit load maximum, and without using repeaters.
