1 Introduction  
Ordering Information  
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.

Contents  
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 are possible. The remaining  
serial information is interpreted as four bits of binary  
data. The valid transmission (VT) output goes high on  
the MC145027 when two conditions are met. First, two  
addresses must be consecutively received (in one  
encoding sequence) which both match the local address.  
Second, the 4 bits of data must match the last valid data  
received. The active VT indicates that the information at  
the Data output pins has been updated.
