HT12E Encoder IC

SPI Module of Arduino. The Encoded 12 bit output data can be obtained from this pin. We should set the bits in same pattern on Encoder and Decoder IC to pair them. The IC has a built in oscillator. It is mainly used in interfacing RF and infrared circuits. Whenever an active low signal is applied at its TE pin then only the parallel data gets transferred serially at the output, otherwise the IC is in high impedance state.

Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Virgin Galactic — Commercial Space Flight. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.

An LED can also be connected across this terminal to indicate output. Used for interfacing RF circuits generally MegaHz. If you want security you can connect any of the 8 pins to 5V to make it high.

Basically found in applications of remote control systems. HT12E IC has four bit parallel data inputwhich it then converts to serial data output. Choosing Motor For Robots. Transmission enable; active low. By continuing to use this website, you agree to their use.

Generally a resistor of value 51 KOhms can be used. What is Web Browser. Gone are the days when we used to use wires to connect two devices to establish a communication path.

A basic connection diagram for the HT12E IC is shown below In the above datashert I have set the 8-bit address data as 0b, by connecting all address pins to ground.

In additional to itit also has 8 address lines which can generally be grounded along with the pin number 9. This pin has to be connected to Ground 0V to enable the Transmission.

These 12 bits are divided into 8 address bits and 4 data bits. This data should be sent to the HT12D for decoding, it can either be sent directly through a wire or by using a wireless medium like RF or IR.

These two ICs together form an Encoder and Decoder pair. For decoding a data the IC will requires an oscillator, luckily this IC has dstasheet in-built. It is very important that your Decoder should datashee have this same address for them to talk to each other.


As soon as TE returns to high, the encoder output completes its final cycle and then stops. Connected to the Ground of circuit. Skip to content Gone are the days when we used to use wires to connect two devices to establish a communication path. This is an CMOS logic integrated circuit encoder. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. They are paired with 2 12 datasehet of decoders for use in remote control system applications.

HT12E is an encoder integrated circuit of 2 12 series ht12d encoders. This IC has a total of 18 pinsnine on either sides: 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.

These are the 8-bit address bits, which is used to protect your data.
