can u check izit this circuit got any problem or not page 9..
thanks

It requires no programming. It allows the transmission of 5 commands, either over an RF or IR link with the appropriate circuits, as shown in the data sheet.

The circuit on pg. 9 looks ok if you want to transmit the signals in the 27MHz RF band.

thx

thanks crutschow for your good information
really useful for me..thanks
