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.

Transmission Timing for HT12E.
These 12 bit parallel data is divided in to 8 address bits and 4 data bits. So out of the bits 8-bits will be endoder to set address and the remaining 4-bit will be used to transmit data.
HT12E & HT12D ENCODER DECODER IC
The encoded bit can be obtained from the Dout pin pin This output cycle will repeats as long as the transmission is enabled.
These are the 8-bit address bits, which is used to protect hy12e data. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. Please read the article 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.
The encoder will be in the Standby mode when the transmission is disabled. Ht1e2 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.
Top menu About Us Contact. Connected to endoder Ground of circuit. The IC is has a wide range of operating voltage from 2. Its power consumption is very low, standby current is 0.
D Flip Flop is primarily meant to provide delay as the output of this Flip Flop is same as Contents1 Components Required2 Circuit Diagram2. This oscillator can be used by connecting these two pins through a 1M Resistor. HT12E — Block Diagram. Skip to main content. The primary function of HT12E is to encode a bit and send it out through the output pin. The IC has a built in oscillator. If you want security you can connect any of the 8 pins to 5V to make it high. A dancing light can be easily constructed using a timer wired in astable mode.
HT12E — Pin Diagram. HT12E is able to operate in a wide voltage range from 2.
Can range from 2. This pin has to be connected to Ground 0V to enable the Transmission. By using the paired HT12E encoder and HT12D decoder we can easily transmit and receive 12 bits of parallel data serially. 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. When the transmission enable TE signal switches to HIGH, the encoder output completes the current cycle and stops as shown above.
For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.
HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet
HT12E simply converts 12 bit parallel data in to serial output ht2e can be transmitted through a RF transmitter. 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.
