• Manufacturer Part Number: SC50560-002
• Description: INFRARED REMOTE CONTROL TRANSMITTER
• Manufacturer: SILAN [Silan Microelectronics Joint-stock]

MODE B
not selected, therefore the transmission code only consists of the 6 bits data code followed by a sync. bit. Please
refer to the diagram below:
KI3 with the Scan Outputs KO0 to KO7, thereby constructing a 4x8 key matrix. When two or more keys are pressed
at the same time, the transmission output Dout is set to and the no transmission occurs. Please refer to the table
below.
NOTE: * = Output of a five-word transmission code.
The diagram below gives us the transmission code format for Mode B. Under this mode, the custom codes are
Under Mode B, a maximum of 32 different instructions may be provided simply by connecting the inputs KI0 to
