HT12E is an encoder integrated circuit of 2 12 series of encoders. The IC is has a wide range of operating voltage from 2. These 12 bits are divided into 8 address bits and 4 data bits. The encoded bit datashset be obtained from the Dout pin pin Supply voltage; 5V 2.

This pin outputs the parallel data serially.

HT12E Encoder IC

These are the 8-bit address bits, which is used to protect your data. These two ICs together form an Encoder and Decoder pair.

As soon as TE returns to high, the encoder output completes its final cycle and then stops. You can know to set up the HT12D after this from here. This pin has to be connected to Ground 0V to enable the Transmission.

Arduino based GPS receiver. This cycle is repeated as long as TE is kept low. Choosing Battery for Robots. Simply put, HT12E converts the parallel inputs into serial output. They are paired with 2 12 series of decoders for use in remote control system applications.


This oscillator can be used by connecting these two pins dtasheet a 1M Resistor. At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel darasheet.

After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer.

HT12A/HT12E – Product Details – Holtek

HT12E has a transmission enable pin which is active low. If you want security you can connect any of the 8 pins to 5V to make it high. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.

SPI Module of Arduino. This high-density System-in-Package SiP integrates controller, power switches, and support components. These pins are generally shorted by a resistor.

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. I am now going to tell you about to control a certain robot wirelessly rather than using wires. This is an CMOS logic integrated circuit encoder.

HT12E IC has four bit parallel data inputwhich it then converts to serial data output. What is Web Browser. 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. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address 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. Gone are the days when we used to use wires to connect two devices to establish a communication path. Choosing Motor For Robots.

It is very important that your Decoder should also have this same address for them to talk to each other. Connected to the Ground of circuit. Virgin Galactic — Commercial Space Flight. HT12E begins datasueet 4-word transmission cycle upon receipt of a transmission enable.

Transmission enable; active low.

HT12E Datasheet

It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. Generally a resistor of value 51 KOhms can be used.
