This IC hasmany applications in short range remote controlling. HT12E has a transmission enable pin which is active low.

Choosing Battery for Robots. The IC has a built in oscillator. The encoded bit can be obtained from the Dout pin pin This pin has to be connected to Ground 0V to enable datashest Transmission. Transmission enable; active low.

This is an CMOS logic integrated circuit encoder. Gone are the days anf we used to use wires to connect two devices to establish a communication path.

It is very important that your Decoder should also have this same address for them to talk to each other. Virgin Galactic — Commercial Space Flight. Basically found in applications of remote control systems.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

Simply put, HT12E converts the parallel inputs into serial output. 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 oc best suited for you. The data on 4 bit th12d type output pins remain unchanged until new is received.

Pull the Transmission Enable pin pin 14 to ground to activate transmission. Thus this helps in setting up oscillations in the IC.


So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc.

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

In additional to itit also has 8 address amd which can generally be grounded along with the pin number 9. Virgin Galactic — Commercial Space Flight. HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders. Can be used in Home automation for short range remote switching Ddatasheet systems like Burglar alarm system, Smoke or Fire alarm system etc.

Skip to main content. TL — Programmable Reference Voltage. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.

In this hf12e 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.

They are paired with 2 12 series of decoders for use in remote control system applications. They are paired with 2 12 series of encoders. In simple terms, HT12D converts the serial input into parallel outputs. An LED can also be connected across this terminal to indicate output.

What is Web Browser. Submitted by admin on 30 October h12d HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits.

HT12D Decoder IC

These 12 bits are divided into 8 address bits and 4 data bits. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.


Choosing Motor For Robots. Arduino based GPS receiver. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins. This pin outputs the parallel data serially. Now first hf12d all let me acquaint you about these two integrated circuits: HT12E begins a 4-word transmission cycle upon receipt of a transmission enable.

These two ICs together form an Encoder and Decoder pair. I am now going to tell ht12r about to control a certain robot wirelessly rather than using wires.

Skip to main content. These are the 8-bit address bits, which is used to protect your data. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data.

HT12D/HT12F – Product Details – Holtek

Andd is mainly provided to interface RF and infrared circuits. HT12E IC has four bit parallel data inputwhich it then converts to serial data output. Darasheet four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits.

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 Encoder IC

Connected to the Ground of circuit. Supply voltage; 5V 2. Interface SD Card with Arduino. Can range from 2.
