433MHz RF transmitter and receiver

hii, im working with on Arduino Nano project and i have to connect the 433MHz RF transmitter and receiver with it. so basically there is two Arduino one for the transmitter and one for receiver but i i heard that for this its a must to have HT12D Decoder IC and HT12E Encoder IC. is it true ? and is there any other way to do this project without the HT12D Decoder IC and HT12E Encoder IC?

thank you
