BL9149 Overview
The BL9149/9150 is CMOS LSI designed for use on the general infrared ray remote control receiver, and when it is used inbination with BL9148, the remote control system can be constructed. The BL9149 is DIP 16 Pin type and is capable of controlling 10functions,while the BL9150 is DIP 24PIN type and is capable of controlling 18 functions. Except these, the principle and the block diagram of the two circuits are almost...
