Thus this helps in setting up oscillations in the IC. They are paired with 2 12 series of decoders for use in remote control system applications. HT12E IC has four bit parallel data inputwhich it then converts to serial data output.

This oscillator can be used by connecting these two pins through a dstasheet Resistor. The primary function of HT12E is to encode a bit and send it out through the output pin. This IC has a total of 18 pinsnine on either sides: Can range from 2.

This is an CMOS logic integrated circuit encoder. Basically found in applications of remote control systems. 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.


The Encoded 12 bit output data can be obtained from this pin. This pin outputs the parallel data serially.

These pins are generally shorted by a resistor. Skip to main content. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. datwsheet

In additional to itit also has 8 address lines which can generally be grounded along with the pin number 9. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. The IC is has a wide range of operating voltage from 2.

Interface GPS with Arduino. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.

Transmission enable; active low. Simply put, HT12E converts the parallel inputs into serial output.

It is mainly used in interfacing RF and infrared circuits. If you want security you can connect any of the 8 pins to 5V to make it high. This cycle is repeated as long as TE is kept low.


I am now going to tell you about to control a certain robot wirelessly rather than using wires. Pull the Transmission Enable pin pin 14 to ground to activate transmission.

It is very important that your Decoder should also have this same address for them to talk to each other. HT12E is an encoder integrated circuit of 2 12 series of encoders.

HT12E Encoder IC

These 12 bits are divided into 8 address bits and 4 data bits. HT12E has a transmission enable pin which is active low. These are the 8-bit address bits, which is used to protect your data. Virgin Galactic — Commercial Space Flight. Arduino based GPS receiver. This ht1e2 has to be connected to Ground 0V to enable the Transmission. As soon as TE returns to high, the encoder output completes its final cycle and then stops.

Gone are the days when we used to use wires to connect two devices to establish a communication path.
