224 OTP ENCODER
DESCRIPTION
The SC9314 is CMOS LSI encoder designed for remote control
system applications. It encodes 24 bits of information and then
serially transmits it via the D
enable (DATA pins: D0~D3) signals. The combination of address
and bits of the SC9314 is designed by a one-time programmable
process. The chip, in addition, offers various packaging for flexible
combination of programmable address/data so as to meet various
applications. Its programmable address/data is transmitted together
with the anti-code bits via RF or infrared transmission medium upon
receipt of a trigger signal.
FEATURES
* Operating voltage: 2V~12V
* Low power consumption
* Built-in oscillator needs only 5% resistor
* 0/2/4/8 data selectable
