The Renesas Electronics 3.3V, Half Duplex, 250kbps Slew Rate Limited, RS-485/RS-422 Transceiver. These single transceiver that meet both the RS-485 and RS-422 standard for balanced communication. It uses slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission line, or unterminated stubs in multidrop and multipoint application.in the logic input accept signal in excess of 5.5V and make them compatible with 5V logic.

-7V to +12V common-mode input voltage range
Three-state Rx and Tx outputs
10ns propagation delay, 1ns skew
Full duplex and half duplex pinouts
Current limiting and thermal shutdown for driver overload protection
