MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145026/D Encoder and Decoder Pairs CMOS These devices are designed to be used as encoder/decoder pairs in remote control applications.
The MC145026 encodes nine lines of information and serially sends this information upon receipt of a transmit enable (TE) signal.
The nine lines may be encoded with trinary data (low, high, or open) or binary data (low or high).
The words are transmitted twice per encoding sequence to increase security.
The MC145027 decoder receives the serial stream and interprets five of the trinary digits as an address code.
Thus, 243 addresses are possible.
If binary data is used at the encoder, 32 addresses...
