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.

Top menu About Us Advertise. 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 primary function of HT12E is to encode a bit and send it encodee through the output pin.

HT12E Encoder IC

Connected to the Ground of circuit. You can know to set up the HT12D after this from here. Working Flowchart of HT12E.

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. If you want security you can connect any of the 8 pins to 5V to make it high.

The encoder will be in the Standby mode when the transmission is disabled. HT12E — Block Diagram.

Please read the article Skip to main content. It is very important that your Decoder should also have encoded same address for them to talk to each other. Top menu About Us Contact.


It is commonly used for radio frequency Ht21e applications. These two ICs together form an Encoder and Decoder pair. 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.

By using the paired HT12E encoder and HT12D decoder we can easily transmit and receive 12 bits of parallel data serially. This pin has to be connected to Ground 0V to enable the Transmission.

The Encoded 12 bit output data can be obtained from this pin. 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.

Can range from 2. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. This oscillator can be used by connecting these two pins through a 1M Resistor.

Pull the Transmission Wncoder pin pin 14 to ground to activate transmission. The IC is has a wide range of operating voltage from 2.

So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. Contents1 Components Required2 Circuit Diagram2. This output cycle will repeats as long as ht12r transmission is enabled. These are the 8-bit address bits, which is used to protect your data. These four ebcoder are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. HT12E — Pin Diagram. The 4-bit data that has to be encodeg 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.

They can also be connected to switches to manually send and receive data. HT12E is able to operate in a wide voltage range from 2. The encoded bit can be obtained from the Dout pin pin We should set the bits in same pattern on Encoder and Decoder IC to pair them.

Its power consumption is very low, standby current is 0.
