SC9012
INFRARED REMOTE CONTROL TRANSMITTER OF 9012 CODE FORMAT
DESCRIPTION
SC9012 is an infrared remote control transmitter utilizing CMOS
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.
The pin assignments and application circuit are optimized for easy PCB
Layout and cost saving advantage. SC9012 is housed in a 20-pins SO
package.
