HT12E Encoder IC | HT12E Datasheet | Pin Diagram & Description

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

Interface GPS with Arduino. This pin has to be connected to Ground 0V to enable the Transmission.

It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. Supply voltage; 5V 2. They can also be connected to switches to manually send and receive data. It is mainly used in interfacing RF and infrared circuits. As soon as TE returns to high, the encoder output completes its final cycle and then stops.

The IC is has a wide range of operating voltage from 2. Thus this helps in setting up oscillations xatasheet the IC.


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. Choosing Motor For Robots.

HT12E Encoder IC

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. An LED can also be connected across this terminal to indicate output. This IC has a total of 18 pinsnine on either sides: TL — Programmable Reference Voltage. 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.

Basically found in applications of remote control systems. Now first of all let me acquaint you about these two integrated circuits: Gone are the days when 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.

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

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.

The Encoded 12 bit output data can be obtained from this pin. Datassheet additional to itit also has 8 address lines which can generally be grounded along with the pin number 9. Virgin Galactic — Commercial Space Flight.


HT12A/HT12E – Product Details – Holtek

These pins are generally shorted by a resistor. Arduino based Dataheet receiver. By continuing to use this website, you agree to their use. Can range from 2.

These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. These are the 8-bit address datasyeet, which is used to protect your data. To find out more, including how to control cookies, see here: Submitted by admin on 30 October HT12E has a transmission enable pin which is active low.

Used for interfacing RF circuits generally MegaHz. HT12E is an encoder integrated circuit of 2 12 series of encoders. SPI Module of Arduino. This cycle is repeated as long as TE is kept low.

HT12E begins a 4-word transmission cycle upon receipt of a datashset enable. Simply put, HT12E converts the parallel inputs into serial output. This high-density System-in-Package SiP integrates controller, power switches, and support components.

At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data. 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 circuit.
