Special Circuits (continued) Remote Control (continued) Encoder/Decoder Pairs (CMOS) MC145026 Encoder MC145027 Decoder MC145028 Decoder MC145029 Decoder The MC145026 encodes nine bits of information and serially transmits this information. The nine inputs may be encoded with trinary data (0, 1, open) to all 39 (19,683) different codes. The three decoders receive the 9-bit word and interpret some of the bits as address codes and some as data. The MC145027 interprets the firstfive transmitted bits as address and the last four bits as data. The MC 145029 interprets the first four transmitted bits as address and the last five bits as data. The MC 145028 treats all nine bits as address.
