AI Thread Summary
The discussion centers on the search for a datasheet for the IC 576002-3, a two-wire differential digital transmitter. This device features three output states (high, low, ground) and has trapezoidal differential outputs. It is housed in a 28-pin surface mount package with 50 mil centers, potentially indicating a custom design for specific applications in aeronautics and system-to-system data transmission. The possibility of the IC being discontinued or replaced by a custom part is noted, along with the challenge of finding specifications due to its unique communication standard. Overall, the lack of available datasheets suggests it may be a specialized component with limited public documentation.

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.
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
