Each driver and receiver has separate input and output pins for full-duplex bus munication designs. They are designed for balanced transmission lines and interoperation with ANSI TIA/EIA-485A, TIA/EIA-422-B, ITU-T v.11, and ISO 8482:1993 standard-pliant devices. The SN65HVD30, SN65HVD31, and SN65HVD32 are fully enabled with no external enabling pins. The SN65HVD33, SN65HVD34, and SN65HVD35 have active-high driver enables and active-low receiver enables. A low (less than 1 μA) standby current can be achieved by disabling both the driver and...
