Detailed Description

MC145027DWR2 transferred to Lansdale Semiconductor on 07-Oct-2005.
MC145027DW, MC145027P transferred to Lansdale Semiconductor on 30-Sept-2005.
This device is designed to be used as an encoder/decoder pair in remote control applications.
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.
