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(VDD=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.
