Hi,

Could that be one of the famous waveform generator chips.

Do you have a schematic of this circuit or can make one? We could probably tell from that.

 

Welcome to AAC.

What device is this IC in?

A candidate is the Harris Semiconductor 8038, but without knowing the application and/or seeing the other side of the board where the traces are, it's not possible to provide a confidence level. Even though the chip seems to have an "HS", I have never seen, and cannot find an example of, Harris using that logo.

Hi,

Beat ya to it (ha ha).
But maybe it is a fake 8038 chip.
I'd like to see a schematic of the circuit, that would tell all.

Here is the layout. U1 - U4 is that ic. What I know is, that ic is from Siemens.
This circuit is different from the picture but the ic is the same.

 

Unfortunately, that PCB layout is just a breakout board for the chips so it adds nothing, except, that Vcc and Vss are on pins 7 and 14, so it could be an SN7405 six way hex inverter.

Well we need the actual circuit.
Also, resistor values could help a lot.

And a badly designed one at that... the decoupliing caps should be at the start of the power traces, nearer the board edge. They're doing nothing for U1 & U2, they're placed for artistic balance than real-world noise suppression.
