50 Mbps half-duplex RS-485 transceiver for 3.3V industrial buses
Rated for 50 Mbps, this transceiver supports high-speed data links such as backplane communication or high-resolution encoder feedback where the bus clock runs in the tens of megahertz. The 3.3V supply rail matches common FPGA, MCU, and DSP I/O banks directly, eliminating a level-shifter on the bus interface. The 80 mV receiver hysteresis provides a clean logic threshold on differential lines subject to ground shifts or coupled noise — a practical margin for cables running alongside motor power feeds.
For dual-sourcing planning, the base product number 65HVD78 covers multiple package and temperature variants in the same family.
