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.

HT12E Encoder IC | HT12E Datasheet | Pin Diagram & Description

These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. This high-density System-in-Package SiP integrates controller, power switches, and support components.

This cycle is repeated as long as TE is kept low. HT12E is an encoder integrated circuit of 2 12 series of encoders. You can know dqtasheet set up the HT12D after this from here. They are paired with 2 12 series of decoders for use in remote control system applications.

The IC has a built in oscillator. Supply voltage; 5V 2.

HT12A/HT12E – Product Details – Holtek

Submitted by admin on 30 October These 12 bits are divided into 8 address bits and 4 data bits. These are the 8-bit address bits, which is used to protect your data. For decoding a data the IC will requires datasjeet oscillator, luckily this IC has one in-built. In dataaheet image I have made all four data bits as zero lowwhen this is decoded we will get the same kind of bits on the output side of HT12D, similarly we can make any changes on these 4-bits and they will be reflected on the output side of the HT12D decoder IC.


The primary function of HT12E is to encode a bit and send it out through the output pin. SPI Module of Arduino. Virgin Galactic — Commercial Space Flight. In the above circuit I have set the 8-bit ij data as 0b, by connecting all address pins to ground. This oscillator can be used by connecting these two pins through ht1e 1M Resistor. Transmission enable; active low.

Connected to the Ground of circuit. This pin has to be connected to Ground 0V to enable the Transmission. Choosing Battery for Robots.

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. Arduino based GPS receiver.

HT12E Encoder IC

HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. HT12E has a transmission enable pin which is active low. Skip to main content. Choosing Motor For Robots.

It is very important that your Decoder should also have this same address for them to talk to each other. Interface SD Card with Arduino. If you want security you can connect any of the 8 pins to 5V to make it high. The Encoded 12 bit output data can be obtained from this pin. These two ICs together form an Encoder and Decoder pair.


TL — Programmable Reference Voltage. As soon as TE returns to high, the encoder output completes its final cycle and then stops. The encoded bit can be obtained from the Dout pin pin Can range from 2. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. We should set the bits in same pattern on Encoder and Decoder IC to pair them. Simply put, HT12E converts the parallel inputs into serial output.

It is mainly used in interfacing RF and infrared circuits. What is Web Browser. They can also be connected to switches to manually send and receive data. A basic connection diagram ddatasheet the HT12E IC is shown datasheett In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. 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. The IC is has a wide range of operating voltage from 2.

Pull the Transmission Enable pin pin 14 to ground to activate transmission.
