INFRARED REMOTE CONTROL
RECEIVER
DESCRIPTION
SC9149A/SC9150A
The SC9149A/SC9150A are CMOS LSIs designed for use on the
infrared remote control receiver, and when this LSI is used in
combination with SC9148A for transmitter, the remote control
system can be constructed. The SC9149A is DIP-16 type and is
capable of controlling 10 functions, while the SC9150A is DIP-24
type and is capable of controlling 18 functions.
DIP-16
SC9149A
FEATURES
* Able to output parallel multiple keying signals sent from the
transmitter (The SC9149A is able to output parallel up to 5
functions, while the SC9150A is able to output parallel up to 6
functions.)
* Output for single pulse, hold pulse and cyclic pulse are provided.
(cyclic pulse is available only for SC9150A)
* A single terminal type oscillator by means of CR is provided.
* Code detection circuit provided for code check with the
transmitter prevents inter-ferences from various types of
machines and apparatus.
