FOR INFRARED REMOTE CONTROL
TRANSMITTER
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.
