Application Note: Encoder And Decoder Comparison

Encoders and decoders are an ideal way of sending on/off data, such as button presses, to a remote location. When a line on the encoder is taken high, it will create a data stream that is sent to the decoder. The decoder will interpret the data stream and take a corresponding data line high to replicate the state of the encoder. This article gives an overview of encoder/decoder ICs and explains their similarities and differences.
