HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

The Encoded 12 bit output data can be obtained from this pin. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. This oscillator can be used by connecting these two pins through a 1M Resistor.

Connected to the Ground of circuit.

This oscillator can be used by connecting these two pins through a 1M Resistor 17 Valid Transmission VT This pin will go high when a data is received. It is not mandatory to use it. The encoded bit can be obtained from the Datashet pin pin Thanks a lot for helping us to maintain competitive prices.

For decoding a data the IC will datashfet an oscillator, luckily this IC has one in-built.

HT12E Datasheet

They can also be connected to LED to physically view the received data. What is Web Browser. Buy 15 or more pieces to get Free Shipping Option Availability: The IC has a built in oscillator.

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. This pin powers the IC should use only 5V. This oscillator can be used by connecting these two pins through a 1M Resistor.

This cycle is repeated as long as TE is kept low. Return and Refund Policy. They can also be connected to switches to manually send and receive data. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.

Submitted by admin on 30 October This Datasheef are paired with each other.

HT12E Encoder IC

It is very important that your Decoder fatasheet also have this same address for them to talk to each other. Interface GPS with Arduino. If you want security you can connect any of the 8 pins to 5V to make it high. This pin has to be connected to Ground 0V to enable the Transmission. The primary function of HT12E is to encode a bit and send it out through the output pin.

HT12E has a transmission enable pin which is active low. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to ht12 data. This pin will go high when a data is received.

So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. Full Name Email Address. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins datasneet ground.

Simply put, HT12E converts the parallel inputs into serial output. The IC is has a wide range of operating voltage from 2. Actual product may vary from the product photograph displayed above. As soon as TE returns to high, the encoder output completes its final cycle and then stops.
