MC145027P - Decoder

This device is designed to be used as a decoder in remote control applications. For the encoder component, see MC145026.

The MC145027 decoder receives the serial stream and interprets five of the trinary digits as an address code, so 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 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.
