MC145028三态编解码芯片Pdf资料

应用功能： 三态编解码芯片 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 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.
