What doc you need?

Its simple the OUTPUT of TSOP Goes LOW when it detects 38KHz IR thats it !!!

There is this lovely site, which some say, is planning for world domination... But that aside, maybe it can help you. I keep forgetting its exact name. It think it starts with a "G" ends with an "E" and somewhere inside it has two consecutive "O"s and another "G" followed by an "L".

Hope this helps,

Its in the keywords, baby!

If you can draft a search string that is closest to what you are looking for then Google gives you what you want on the first page itself, 9 times out of 10.

I searched for:
1. "How to use TSOP1738"
2. "Forum TSOP1738"
3. "Resources TSOP1738"
4. "Receiver TSOP1738"

All gave me pretty good results.

I typed in tsop1738 into Google.
Google promptly dumped 50,000 results in 0.44 secs. (http://www.roboticsindia.com/About%2050,000%20results%20%280.44%20seconds%29) Most of them were Datasheet download links.
There were circuits About 2,560 results (0.14 seconds) (http://www.google.co.in/images?hl=&q=tsop1738&rlz=1B3GGGL_enIN321IN321&um=1&ie=UTF-8&source=univ&ei=31kJTMjTDYjBcfW32LEO&sa=X&oi=image_result_group&ct=title&resnum=6&ved=0CDwQsAQwBQ) most of which were highly graphical and most useful TSOP1738 circuits indeed.

...took me quite some time to go through some of them !
