Renesas Electronics ISL83071EIBZA-T Line Transceiver

The Renesas RS-485/RS-422 Transceiver is BiCMOS 3.3V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. These devices have very low bus currents (+125μA/-100μA) 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.

Single 3.3V supply
High data sates up to 20Mbps
-7V to +12V common mode input/output voltage range
half and full duplex pinouts
Three state Rx and Tx outputs available
Current limiting and thermal shutdown for driver overload protection
