INFRARED REMOTE CONTROL

RECEIVER

DESCRIPTION

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.

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.
