  • SN65HVD1176: Power dissipated by the driver used with a long cable

    TI Thinks Resolved
    Part Number: SN65HVD1176 Hello, I would like to evaluate the dissipated power by the driver over a long cable (1km). Using this link https://e2e.ti.com/blogs_/b/analogwire/posts/how-to-calculate-the-power-dissipation-of-high-speed-rs-485-transceivers ,…

  • SN65HVD1176: Part-to-Part propagation time variance

    Part Number: SN65HVD1176 Assuming the exact same input was driving infinite SN65HVD1176 RS-485 transceivers, and the single-ended input went from 0 to 3.3v, if measuring the output of each driver on a scope what would be the maximum time between the first…
