SN65HVD07DR — 5V RS485 transceiver for industrial serial links
The 35 mV of receiver hysteresis provides a clean noise margin on long cable runs typical in factory automation, building management, and PLC-to-sensor links.
1 Mbps data rate — enough for most sensor and actuator busses
At 1 Mbps this transceiver covers Modbus RTU, Profibus DP at lower baud rates, and most proprietary RS-485 fieldbus protocols. It will not support the 10 Mbps+ needed for some vision-system or high-speed encoder links, but for temperature controllers, VFDs, and remote I/O racks the margin is fine. The half-duplex architecture means the driver and receiver share the bus pair; firmware must manage the direction pin (DE/RE) to avoid contention.
Industrial temperature, 5V-only supply
The 4.5V minimum supply means a 5V rail with 10% tolerance still keeps the part in spec, but 3.3V logic systems need a level translator on the digital side — the transceiver itself does not accept 3.3V on the supply or bus pins.
TI lists the SN65HVD07DR as Active.
