These are the 8-bit address bits, which is used to protect your data.
HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet
We should set the bits in same pattern on Encoder and Decoder IC to pair them. Connected to the Ground of circuit. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits.
This pin has to be gt12e to Ground 0V to enable the Transmission. The IC has a built in oscillator.
This oscillator can be used by connecting these two pins through a 1M Resistor. The Encoded 12 bit output data can be obtained from this pin. Can range from 2. These two ICs together form an Encoder and Decoder pair.
So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. 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. The primary function of HT12E is to encode a bit and send it out through the output pin.
The Datasheft is has a wide range of operating voltage from 2. Datasbeet the Transmission Enable pin pin 14 to ground to activate transmission. 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 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 is very important that your Decoder should also have this same address for them to talk to each other.

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. If you want security you can connect any of the 8 pins to 5V to make it high. They can also be connected to switches to manually send and receive data.
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 ddatasheet 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.
ut12e The encoded bit can be obtained from the Dout pin pin 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. You can know to set up the HT12D after this from bt12e. Submitted by admin on 30 October A basic connection diagram for the HT12E IC is shown below In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.
Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. TL — Programmable Reference Voltage.
