This sounds like an RS232 interface chip?
If that is the case, then there are plenty of RS232 chips to choose from.
IE:
MAX232.

if you are in such a hurry why didn't you attach the circuit diagram.

This is great ... first we search for your circuit in Google, we then find a solution to your problem....

Is this your first project ??? I assume this must be some college homework.

The said Ic's are available with me..TX2 and RX2 but costs ..a bit more..as it comes in a complete remote control kit. Let me know if you are ready to spend on your project or expect to be FREE?...Also what are the value of Inductors?....Did your lecturer gave you the circuit or you designed it yourself?...Then post it here.....Cheers

I Guess explaining the soldering and desoldering techniques is a bit difficult task as it purely depend on ones own knowledge, skill and practice in the same. If the IC is a DIP package, it can be easily removed with a soldering gun and a desoldering pump. You may also use a desoldering braid or wick instead of the pump if you are experienced. You get ample tutorials with illustrations about how to do it. BTW you may search "Youtube" for video's on the subject. Cheers
