Renesas Electronics ISL83075EIBZA Octal-Channel Line Transceiver

The Renesas Electronics 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, 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 32 unit load maximum, and without using repeaters.

Half and full duplex pinouts
Three state Rx and Tx outputs available
Current limiting and thermal shutdown for driver overload protection
