SC9148B
INFRARED REMOTE CONTROL TRANSMITTER USED TOGETHER WITH
SC9149
DESCRIPTION
The SC9148B is CMOS LSI developed for use on the infrared remote
control transmitter. This LSI has 18 functions, and total 75 commands
can be transimitted : 63 commands by the continuous keys of multiple
keyings is possible and 12 commands by the single shot keys.
FEATURES
* Wide operating voltage range(V
DD
=2.2V ~ 5.0V)
* CMOS structure assures extremely low power dissipation
* Mulitiple keying is possible
* Less external parts
* Adaptable to other Models as Code Bits are available
* An oscillator can be constructed only by connecting an LC or
Ceramic Resonater as the oscillation circuit is housed.
