Mystery IC, 576002-3

  1. Jul 3, 2008 #1
    I'm searching for a datasheet.

    This IC device is a two-wire, differental, digital transmitter.
    Each leg has three output states (hi, lo, gnd).
    The otputs are differential and trapizoidal in shape.

    The logo on the chip is a solid white triangle with the point upward. And a Google search has let me down.

    What package?

    DIL, SM, how many pins?

    What's it out of?

    I'm not sure how the packaging matters, but there are two channels in a package.

    The package is about a 28 pin surface mount, 50 mil centers.

    It's used in aeronautic, system to system data transmission.

    It's very possible this is a custom made IC for a specific application. There may be no specs available, except for engineers that designed the circuit.

    Thanks, Wadt. That could very well be--even as an IC that's been discontinued, to be replaced by a custom part. It seems to support a odd communication standard.
