Product Summary

The MC145026P is a encoder/decoder pair in remote control applications. The MC145026P 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 of the MC145026P are transmitted twice per encoding sequence to increase security.
