In this datasheef 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 xatasheet make any changes on these ht12ee and they will be reflected on the output side of the HT12D decoder IC. HT12E is an encoder integrated circuit of 2 12 series of encoders.

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. The encoded bit can be obtained from the Dout pin pin HT12E has a transmission enable pin which is active low. They can also be connected to switches to manually send and receive data. The primary function of HT12E is to encode a bit and send it out through the output pin.

Simply put, HT12E converts the parallel inputs into serial output. Pull the Transmission Enable pin pin 14 to ground to activate transmission. This oscillator can be used by connecting these two pins through a 1M Resistor. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.


The IC has a built in oscillator. This cycle is repeated as long as TE is kept low. We should set the bits in same pattern on Encoder and Decoder IC to pair them. 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.

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. 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.

You can know to set up the HT12D after this from here. Arduino based GPS receiver. Submitted by admin on 30 October They are paired with 2 12 series of decoders for use in remote control system applications. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. Skip to main content. Transmission enable; active low. What is Web Browser. Interface GPS with Arduino. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.

TL — Programmable Reference Voltage.

HT12E Encoder IC

The IC is has a wide range of operating voltage from 2. Choosing Motor For Robots.

Supply voltage; 5V 2. This pin has to be connected to Ground 0V to enable the Transmission. Can range from 2.


HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

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. Connected to the Ground of dtasheet.

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 are the 8-bit address bits, which is used to protect your data. These 12 bits are divided into 8 address bits and 4 data bits. This high-density System-in-Package Datqsheet integrates controller, power switches, and support components.

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. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. It is mainly used in interfacing RF and infrared circuits. Virgin Galactic — Commercial Space Flight.

As soon as TE returns fatasheet high, the encoder output completes its final cycle and then stops. These two ICs together form an Encoder and Decoder pair. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits.
