I AM WORKING ON MY NEW AFTER MARKET DESIGN BUT I FACED ONE PROBLEM DUE TO UNKNOWN IC
THE IC HAS MARKING 77MO234Q (MAKER -TAXAS ) 8 PIN IC but i have no part number of that ic please solve my problem
I am working on this and I beleive that the device you have is the TLC2272 (either the A or non A version for Automotive). If you could provide me with a close up picture of the device I can be more certain.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to wasim akram95017:
I am sorry that the answer isn't as easy to come up as you might have expected. But I am on a wild chase since there are so many variables that I do not know.
u can see picture of that 8 pin (smd)ic .
the ic has texas instrumentaion logo .logo texas map
first line RIGHT SIDEwith "texas logo" mark as 77
and second line mark M0234Q(WITHOUT ANY GAP).
THERE ARE NO "TI" SYMBOL AND NO ANY OTHER MARK.
i got another same ic
the marking on the ic is
first line with texas logo is 78
and second line is M0234Q
so ,now can i say that marking is M0234Q?
I was able to find someone that tracked down which device this was. The "77" and "78" line indicates that the two devices were made in July 2007 and August 2007 respectively. Since then they have change the symbol to include more information and that is why I was unable to find it.
There are two different dies, I am currently checking to make sure that there is no difference between the device you have and the TLC2272.
thanks for your searching.
i will use your ic.
but i have one query ..
as i know that is MANUFACTURE OF IC-M0234Q is texas
but there are no any information of that ic ,why ?
