ENCODER HT12E PDF

The HT12E is a 2^12 encoder in 18 pin DIP package. This is CMOS LSI for remote control system applications. It is capable of encoding information which. The HT12E Encoder ICs are series of CMOS LSIs for Remote Control system applications. They are capable of Encoding 12 bit of information which consists of 8. HT12E Encoder IC can be used only with its pair HT12D. These two ICs together form an Encoder and Decoder pair.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

This oscillator can be used by connecting these two pins through a 1M Resistor. Working Flowchart of HT12E. The primary function of HT12E is to encode a bit and send it out through the output pin.

Top menu About Us Contact. The 4-bit data that has bt12e 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.

It ht12r very important that your Decoder should also have this same address for them to talk to each other. The encoded bit can be obtained from the Dout pin pin The encoder will be in the Standby mode when the transmission is disabled. D Flip Flop is primarily meant to provide delay as the output htt12e this Flip Flop is same as They can also be connected to switches to manually send and receive data.

HT12E & HT12D ENCODER DECODER IC

Pull the Transmission Enable pin pin 14 to ground to activate transmission. In htt12e above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. A dancing light can be easily constructed using a timer wired in astable mode.

HT12E is able to operate in a wide voltage range from 2. It is commonly used for radio frequency RF applications.

HT12E Encoder IC for Remote Control Systems – Datasheet

So if you are working on a project which has to transmit a 4-bit data from one end to ut12e either by wire or wireless then this IC pair will be best suited for you. These are the 8-bit address bits, which is used to protect your data.

If you want security you can connect any of the 8 pins to 5V h1t2e make it high. Its power consumption is very low, standby current is 0. These 12 bit parallel data is divided in to 8 address bits and 4 data bits.

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 ht12f make any changes on these 4-bits and they will be reflected on the output side of the HT12D decoder IC.

Connected to the Ground of circuit. By using the paired HT12E encoder and HT12D decoder we can easily transmit and receive 12 bits of parallel data serially. HT12E — Block Diagram. The Encoded 12 bit output data can be obtained from this pin.

The IC has a built in oscillator. Top menu About Us Advertise.

So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same enfoder bits. By using these address pins we can provide 8 bit security code for data transmission and multiple receivers may be addressed using the same transmitter.

Can range from 2.

HT12E Encoder IC

HT12E simply converts 12 bit parallel data in to serial output which can be transmitted through a RF transmitter. These two ICs together form an Encoder and Decoder pair. We should set the bits in same pattern on Encoder and Decoder IC to pair them. Please read the article Skip to main content. This output cycle will repeats encoddr long as the transmission is enabled. This pin has to be connected to Ground 0V to enable the Transmission.

The HT12E 2 12 series encoder starts a 4 word encoded cycle upon receiving transmission enable signal on TE input.

Transmission Timing for HT12E. You can know to set up the Encpder after this from here. The IC is has a wide range of operating voltage from 2.
