HT12E Encoder IC can be used only with its pair HT12D. These two ICs together form an Encoder and Decoder pair. Buy HOLTEK HT12E online at Newark element Buy your HT12E from an authorized HOLTEK distributor. HT12E is a series encoder IC (Integrated Circuit) for remote control applications. It is commonly used for radio frequency (RF) applications. By using the.

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. Transmission Timing for HT12E. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. The primary function of HT12E is to encode a bit and send it ht12ee through the output pin. A team of researchers from University of Pennsylvania led by Nader Engheta are working on the ways to use Working Flowchart of HT12E.

In this image I have made all four data bits bt12e 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 ht21e be reflected on the output side of the HT12D decoder IC.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

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. HT12E — Pin Diagram.


If you want security you can connect any of the 8 pins to 5V to make it yt12e. Top menu About Us Advertise. The IC has a built in oscillator. We should set the bits in same pattern on Encoder and Decoder IC to pair them.

We all know that a Solar Panel can be used to convert light energy to electrical energy. The encoder will be in the Standby mode when the transmission is disabled. Its power consumption is very low, standby current is 0.

HT12E is able to operate in a wide voltage 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. The HT12E 2 12 series encoder starts a 4 word transmission cycle upon receiving transmission enable signal on TE input.

Top menu About Us Contact. 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. Skip to main content. Can range from 2. They can also be connected to switches to manually send and receive data.

HT12E Encoder IC for Remote Control Systems

HT12E simply converts 12 bit parallel data in to serial output which can be transmitted through a RF transmitter. Pull the Transmission Enable pin pin 14 to ground to activate ut12e. When the transmission enable TE signal switches to HIGH, the encoder output completes the current cycle and stops as shown above.

Connected to the Ground of circuit. The encoded bit can be obtained from the Dout pin pin These 12 bit parallel data is divided in to 8 address bits and 4 data bits. It is h12e important that your Decoder should also have this same address for them to talk to each other. This pin has to be connected to Ground 0V to enable the Transmission.

Optical Transistors Out of Silicon: This oscillator can be used by connecting these two pins through a 1M Resistor. HT12E — Block Diagram. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. The IC is has a wide range of operating voltage from 2.

You can know to set up the HT12D after ht12f from here. For some time now Intel had been trying to enter the smartphone sector owing to the success when it Light in place of Electricity!!!!! This output cycle will repeats as long as the transmission is enabled. It is commonly used for radio frequency RF applications.

For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. The 4-bit data that has to be ht1e 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. By using the paired HT12E encoder and HT12D decoder we can easily transmit and receive 12 bits of parallel data serially.
