hello.. i got a question to ask abt encoder. i am using a HT12E that consist of 8 address bits and 4 data/address bits. If i want to expand the encoder so that there cld be more functions, say about 8 data bits, must i expand the address bits as well? or do any of u have recommandations on what encoder i should use? because i have searched the web on the various types of encoders but they all seem to have only 4 data bits. thanks alot. pls help...
