hi every one

I have recently discovered that my local electronics store sells a transmitter and receiver both operating at 433 Mhz. I know for sure that they work with a PIC but i am  not sure if they will work with a Mega.

For the transmitter i am guessing i will hook up power and ground and connect the tx line to the data out put. As in the following data sheet. and the antenna to ANT

As for the reciever i am not sure as there are 2 Data lines?

My main question is would it be possible for me to use these with a Avr, i have been told that they are reliable, have a range up to 100m and for the both of them are only 26 dollars.

Thanks for your time

If they work with a PIC then they should work fine with an AVR. They are a basic OOK pair so whatever digital state the Tx input is, the Rx output should match - provided you don't exceed the maximum data rate.

Those two data lines are connected internally, so you can pick and choose between which one you will use since it won't matter.
