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.

Skip to main content. It is commonly used for radio frequency RF applications.

This pin has to be connected to Ground 0V to enable the Transmission. The HT12E 2 12 series encoder starts a 4 word transmission cycle upon receiving transmission enable signal on TE input. HT12E — Pin Diagram. Connected to the Ground of circuit.

The primary function of HT12E is to encode a bit and send it out through the output pin. You can know to set up the HT12D after this from here. 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.

So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. HT12E is able to operate in a wide voltage range from 2.

Jt12e you want security you can connect any of the 8 pins to 5V to make it high. It is very important that your Decoder should also have this same address for them to talk to each other.


Its power consumption is very low, standby current is 0. We all know that a Solar Panel can be used to convert light energy to electrical energy. Top menu About Us Advertise. When the transmission enable TE signal switches to HIGH, the encoder output completes the current cycle and stops as shown above. The IC has a built in oscillator. The encoder will be in the Standby mode when the transmission is disabled. Optical Transistors Out of Silicon: These two ICs together form an Encoder ht12d Decoder pair.

Can range from 2. A team of researchers from University of Pennsylvania led by Nader Engheta are working on the ways to use 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.

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. Pull ht1e Transmission Enable pin pin 14 to ground to activate transmission. Working Flowchart of HT12E. HT12E simply converts 12 bit parallel data in to serial output which can be transmitted through a RF transmitter. These 12 bit parallel data is divided in to 8 address bits and 4 data bits.

These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. This output cycle will repeats as long as the transmission is enabled. By using the paired Ht12f encoder and HT12D decoder we can easily transmit and receive 12 bits of parallel data serially. 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 encoded bit can be obtained from the Dout pin pin These are the 8-bit address bits, which is used to protect your data.

They can also be connected to switches to manually send and receive data. The Encoded 12 bit output data can be obtained from this pin.

We should set the bits in same pattern on Encoder and Decoder IC to pair them. In this image I have made all four data bits as zero lowwhen this is decoded th12e 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.


For some time now Intel had been trying to enter the smartphone sector owing to the success when it This oscillator can be used by connecting these two pins through a 1M Resistor. Light in place of Electricity!!!!! The IC is has a wide range of operating voltage from 2. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. 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.
