SC9148A
SC9148A is FOR INFRARED REMOTE CONTROL TRANSMITTER manufactured by Silan Semiconductors.
DESCRIPTION
The SC9148A is CMOS LSI developed for use on the infrared remote control transmitter. This LSI has 18 functions, and total 75 mands can be transimitted : 63 mands by the continuous keys of multiple keyings is possible and 12 mands by the single shot keys.
SOP-16
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.
