ElecSuper SN65HVD72DR(ES)

SN65HVD72DR is a 3.0V~3.6V wide-supply RS-485 transceiver with bus-port ESD protection exceeding 15kV HBM, ±15V bus fault protection, half-duplex, low-power operation, fully compliant with TIA/EIA-485 standard requirements. SN65HVD72DR integrates one driver and one receiver, both independently enable/disable controlled. When both are disabled, the driver and receiver outputs enter a high-impedance state. SN65HVD72DR features 1/8 unit load, allowing up to 256 SN65HVD72DR transceivers to be connected on the same bus. Error-free data transmission up to 250kbps is supported. SN65HVD72DR operates at 3.3V with fail-safe, current-limiting protection, and overvoltage protection features.
