Renesas Electronics ISL4485EIBZ Line Transceiver, BiCMOS

The Renesas Electronics Transceiver is a high speed, BiCMOS 5V powered, single transceiver that meets both the RS-485 and RS-422 standards for balanced communication. The excellent differential output voltage coupled with high drive-current output stages allow 20Mbps operation over twisted pair networks up to 450ft in length.

Three state Rx and TX outputs
30ns propagation delays, 2ns skew
Current limiting and thermal shutdown for driver overload protection
