Automotive RS-422/RS-485 Bus Transceiver, featuring a single transmitter and receiver. This interface IC supports multidrop and multipoint data transmission topologies with differential signal types for both transmitter and receiver. Operating from a single 5V supply (4.5V to 5.5V), it achieves a minimum data rate of 20Mbps. The component is housed in an 8-pin Thin Dual Flat Package No Lead with Exposed Pad (TDFN EP), measuring 3x3x0.73mm, designed for surface mounting. It offers 128 drivers and receivers per line at RS-485, with 3-state driving mode and a wide operating temperature range of -40°C to 125°C.
