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.
