Standalone serial transmission without arduino

I was wondering why aren't there many DIP UART ICs. Now I know that most of them are process oriented i.e. used along with Processors.
The 6404 ic is also an uart (40 pins and I dont need reciver part).

I thought of using Encoder and decoder pair HT12E and HT12D, but i dont know how to implement 8 bit data with two start and stop bits. (about parity, i am not sure).

Is there any way to use encoder and decoders?
( for minimal circuit and like uart standard serial transmission)
