Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.

It is mainly used in interfacing RF and infrared circuits.

HT12E Encoder IC

It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. As soon as TE returns to high, the encoder output completes its final cycle and then stops. We should set the bits in same pattern on Encoder and Decoder IC to pair them.

Supply voltage; 5V 2. This high-density System-in-Package SiP integrates controller, power switches, and support components.

It is very important that your Decoder should also have this same address for them to talk to each other. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. Interface GPS with Arduino. Choosing Battery for Robots.

HT12E is an encoder integrated circuit of 2 12 series of encoders. A basic connection diagram for the HT12E IC is shown below In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.

For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. These 12 bits are divided into 8 address bits and 4 data bits. Transmission enable; active low. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. They can also be connected to switches to manually send and receive data. These two ICs together form an Encoder and Decoder pair.

This oscillator can be used by connecting these two pins through a 1M Resistor.

HT12E Datasheet

The IC is has a wide range of operating voltage from 2. If you want security you can connect any of the 8 pins to 5V to make it high. SPI Module of Arduino. 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.

Choosing Motor For Robots. The Encoded 12 bit output data can be obtained from this pin. TL — Programmable Reference Voltage. The encoded bit can be obtained from the Dout pin pin These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. They are paired with 2 12 series of decoders for use in remote control system applications. Arduino based GPS receiver.

Pull the Transmission Enable pin pin 14 to ground to activate transmission. Simply put, HT12E converts the parallel inputs into serial output.

datasheeet This cycle is repeated as long as TE is kept low. The 4-bit data that has to be sent has to be given to the pins AD0 to AD1 and an address of 8-bit has to be set using the pins A0 to A7.

HT12E has a transmission enable pin which is active low. 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.

Skip to main content. These are the 8-bit address bits, which is used to protect your data. 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. The IC has a built in oscillator.
