The Texas Instruments SN65HVD77DR is a full-duplex RS-485/RS-422 transceiver rated for 50 Mbps signaling on a single 3.3 V rail (3V to 3.6V).
If your system runs a 5 V bus or mixed-voltage backplane, you will need a level translator or a 5 V-tolerant transceiver.
TI lists the SN65HVD77DR as Active.
