SC5262-RF

The SC5262-RF is one member of the SC5262 series.The SC5262 is a remote control encoder paired with SC5272 utilizing CMOS technology.It encodes data and address pins into a serial coded waveform suitable for RF or IR modulation. SC5262 has a maximum of 12-bits of tri-state address pins providing up to 531,441(or 3(12)) address codes; thereby, drastically reducing any code collision and unauthorized code scanning possibilities.

Features of the SC5262-RF are:(1)low power consumption and very high noise immunity; (2)up to 12 tri-state code address pins or 6 data pins; (3)wide operating voltage range(Vcc=3V ~ 15V); (4)single resistor oscillator; (5)latch or momentary output type.In no event shall Sensitron Semiconductor be liable for any damages that may result from an accident or any other cause during operation of the user's units according to the datasheet(s). Sensitron Semiconductor assumes no responsibility for any intellectual property claims or any other problems that may result from applications of information, products or circuits described in the datasheets.

The absolute maximum ratings of the SC5262-RF can be summarized as:(1)supply voltage:-0.3 to 16.0V;(2)storage temperature:-40 to 125;(3)input/output voltage:-0.3 to Vcc+0.3V;(4)operating temperature range:-20 to 70;(5)maximum power dissipation:300 mW.The SC5262 encodes the code address and data set at A0~ A5 and A6/D5 ~ A11/D0 into a special waveform and outputs it to the Dout when TE is pulled to "0" (Low state).This waveform is fed to either the RF modulator or the IR transmitter for transmission. The Transmitted radio frequency or infrared ray is received by the RF demodulator or IR receiver and reshaped to the special waveform. SC5272 is then used to decode the waveform and set the corresponding output pins. Thus completing a remote control encoding and decoding function.A group of Code Bits is called a Code Word. A Code Word consists of 12 AD bits followed by one Sync. Bit.The 12 AD bits are determined by the corresponding states of A0~A5 and A6/D5 ~ A11/D0 pins at the time of transmission. When Data Type of SC5262 is used , the address bits will decrease accordingly.
