INFRARED REMOTE CONTROL
TRANSMITTER
DESCRIPTION
Technology specially designed for use on infrared remote control
applications. It is capable of controlling 32 function keys and 6
double keys. Each system has a maximum of 8 commands; thus,
SC9012 can provide up to a total of 256 commands.
PCB Layout and cost saving advantage. SC9012 is housed in a 20-
pins SO package.
