HT12E Encoder

Br 100.00

  • 12-bit Encoder IC to be used with HT12D
  • Encoded data has 4 Data bits and 8 Address bits (8 4=12-bits)
  • Commonly used for RF and IR wireless transmission
  • Wide supply voltage range from 2.4V to 12V, typically 5V is used
  • Low stand by current of 0.1uA at Vcc=5V
  • Available in 16-pin DIP, 20-pin SOP

  • The IC HT12Ecan be used only with its pair HT12D. These two ICs together form an Encoder and Decoder pair. They are 12-bit Encoders/Decoders, meaning they can transmit 12-bit a data among them. But your encoder IC should not communicate with someone else decoder IC, so an Encoder and Decoder IC pair will share a common Address which is an 8-bit data. So out of the 12-bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.
  • With 4-bit data we can create 16 types (2^4 =16) of combinations. These IC’s are commonly used with RF pairs or IR pairs. So if you are working on a project which has to transmit a 4-bit data from one end to other either by wire or wireless then this IC pair will be best suited for you.

Applications

  • 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..
