RF RECEIVER/DECODER MODULE / 418MHz / NO EXTERNAL RF COMPONENTS REQUIRED

HT12D Decoder 18 DIP IC HT12D Decoder IC is a 212 series for remote control applications manufactured by Holtek. It is commonly used for radio frequency (RF) wireless applications. By using the paired  HT12E encoder and HT12D decoder we can transmit 12 bits of parallel data serially. HT12D simply converts serial data to its input (may be received through RF receiver) to 12 bit parallel data. These 12 bit parallel data is divided into 8 address bits and 4 data bits. Using 8 address bits we can provide 8-bit security code for 4-bit data and can be used to address multiple receivers by using the same transmitter. HT12D is a CMOS LSI IC and is capable of operating in a wide voltage range from 2.4V to 12V. Its power consumption is low and has high immunity an noise. The received data is checked 3 times for more accuracy. It has a built-in oscillator, we need to connect only a small external resistor. HT12D decoder will be in standby mode initially ie, an oscillator is disabled and a HIGH on DIN pin activates the oscillator. Thus the oscillator will be active when the decoder receives data transmitted by an encoder. The device starts decoding the input address and data. The decoder matches the received address three times continuously with the local address given to pin A0 – A7. If all matches, data bits are decoded and output pins D8 – D11 is activated. This valid data is indicated by making the pin VT (Valid Transmission) HIGH. This will continue until the address code becomes incorrect or no signal is received.     Used to convert Parallel 4-bit data  to series data     Highly useful in wireless communication projects involving RF or IR     Remote controlled systems like garage doors, Car alarm system, Car door controls etc.     Can be used in Home automation for short range remote switching     Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. This item is available in stock and is not drop shipped.
