312 Decoder (10+2 - Corresponds to HT6010/HT6012) 312 Decoder (10+2 - Corresponds to HT6010/HT6012) D/N: HA0064E Introduction This application shows how to use the HT48R50A-1 to simulate the HT6032 3 12 decoder function to decode the 10 Address bits and 2 Data bits for the HT6010/HT6012. Function and Theory The 3 Decoder function can decode the 10 Address bits and 2 Data bits each of which can be set individually to either ″1″ and ″0″. MCU: HT48R50A-1 Method: uses the HT6032 decoding process (see the HT6032 datasheet) to check the corresponding signal width to judge if the signal is either a ″0″, ″1″ or ″floating″. The corresponding width can decode skewed signals, the tolerance of which can be adjusted by MAXDURATION in the program.
