I need to figure out which smd class this ic chip is. If you take a look at this pic

The 8 pin chip with the red dot is the one I need to replace. I have an SOIC 8 version sitting just to the left of the chip. Its quite a bit smaller.
any help appreciated Spark

Hi:
Unfortunately your foto doesn't seem to open in my browser. Perhaps if it were placed there again as a jpeg or jpg or the like with a legitimate suffix to match the file type, we will have more luck.

Even increasing the picture size wouldn't allow me to see the writing on the device. Can you post exactly what is on the chip?

BTW, if you're just looking for package info, I believe it's an SO-8.

It took a lot of magnification but
4LC 1728 1Q5 is the number on the chip. I reloaded the pic under a different name. The green arrow points to the IC in question.

Thanks, Spark

SO-8..... That's sounds right from the lit. I've been looking at.
Do you know of an easy way to use an SOIC 20 chip in a 20 pin DIP socket ?
This IC is only available in the SOIC 20. I've seen all kinds of DIP to SOIC sockets but few the other way around. Thanks again, Spark

I'm not sure why you'd want to do such a thing. What exactly are you trying to do? I'm assuming that you need a replacement chip for the board in question, right? If so, what is the function of the board, and what markings are on the chip to the left of the device in question?

The function of the original pc board with the SO-8 chip is a wireless router I'm repairing for a friend. She gave me the SOIC 8 chip to swap out.
I'm sorry, this SOIC 20 question was for a different problem.
I purchased an HIP 4080 (full bridge FET driver) 20 pin DIP to repair another unrelated problem with a car amplifier.
I ordered the IC from Mouser (it seems they were the only ones I could find that carried it as it is discontinued) They sent me the SOIC 20 version of the HIP 4080 and said that is the only version they have.
I now am stuck with making the SOIC 20 work in the circuit. I hope that clarifies my problems. I didn't mean to be confusing but that's my other problem.
thanks again for your help. Spark

I'm not trying to be negative, but I have a hard time believeing reparing a wireless router can be worth the investment of time and money required to fix it unless it is something extremely simple. You can get some routers for almost nothing these days. You can eaisly find a used one on ebay for less than $30. Buy a linksys and put DD-WRT on it and then you have a top notch router and also a cheap fix.

What can I say... She likes the router and got the chip free.
When she asked if I would do it, I said yup because it should only take about 30 seconds of my time. Obviously, it was a miscalculation.
