CMOS LSI use on the general infrared ray remote control receiver , L9150

Description

The BL9149/9150 is CMOS LSI designed for use on the general infrared ray remote control receiver, and when it is used incombination 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 the same.

Features

● Able to output multiple keying signals parallel sent from the BL9148 (The BL9149 is able to output parallel up to 5 functions, while the BLl9150 is up to 6 functions)

● Single pulse, continuous pulse and cyclic pulse outputs are provided, (Cyclic pulse is available only for BL9150)

● A single terminal type oscillator by means of CR is provided.

● Code detection circuit provided for code check with the transmitter preventing interferences form other types.

Applications

Use as remote control transmitters in audios, air conditioners, toys and others.
