ML145026 ML145027 ML145028 Encoder and Decoder Pairs CMOS Legacy Device: Motorola/Freescale MC145026, MC145027, MC145028 These devices are designed to be used as encoder/decoder pairs in remote control applications. The ML145026 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 ML145027 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 ML145027 when two conditions are met. First, two addresses must be consecutively received (in one encoding sequence) wh [ … ]
