Summary
General Infrared Ray Remote Control Receiver
Description
The BL0509/0510 is CMOS LSI designed for use on the general infrared ray remote control receiver, and when it is used in combination with BL9148, the remote control system can be constructed. The BL0509 is DIP 16 Pin type and is capable of controlling 10 functions, while the BL0510 is DIP 24 PIN type and is capable of controlling 18 functions. Except these, the principle and the block diagram of the two circuits are almost the same.
