DATASHEET OF HT12E AND HT12D PDF

HT12E Encoder IC can be used only with its pair HT12D. These two ICs together form an Encoder and Decoder pair. DataSheet: PDF icon HT12E is an encoder integrated circuit of series of encoders. They are paired with series of decoders for use in. DataSheet: PDF icon HT12D is a decoder integrated circuit that belongs to series of decoders. This series of decoders are mainly used for.

HT12E IC has four bit parallel data inputwhich it then converts to serial data output.

HT12D Decoder IC

Choosing Motor For Robots. 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 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.

HT12E has a transmission enable pin which is active low. By continuing to use this website, you agree to their use. They can also be connected to switches to manually send and receive data.

These pins are generally shorted by a resistor. HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

What is Web Browser. This is an CMOS logic integrated circuit encoder. An LED can also be connected across this terminal to indicate output. Dataaheet a resistor of value 51 KOhms can be used. The data on 4 bit latch type output pins remain unchanged until new is received. If you want security you can connect any of the 8 pins to 5V to make it high.

Used for interfacing RF circuits generally MegaHz.

It is very important that your Decoder should also have this same address for them to talk to each other. Thus this helps in setting up oscillations in the IC. Transmission enable; dataasheet low. Supply voltage; 5V 2. 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. Interface SD Card with Arduino.

It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. TL — Programmable Reference Voltage.

The input data code is decoded when no error or unmatched codes are found. A basic connection diagram for the HT12E IC is shown below In the above circuit I have set the 8-bit address data as hf12d, by connecting all address pins to ground. In simple terms, HT12D converts the serial input into parallel outputs. This cycle is repeated as long as TE is kept low.

We should set the bits in same pattern on Encoder and Decoder IC to pair them. The IC is has a wide range of operating voltage from 2. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer.

Basically found in applications of remote control systems. Simply put, HT12E converts the parallel inputs into serial output. Virgin Galactic — Commercial Space Flight. Skip to main content. The encoded bit can be obtained from the Dout th12e pin 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.

Can be used in Home automation for short range remote switching Oc systems like Burglar alarm system, Smoke or Fire alarm system etc. The Encoded 12 bit output data can be obtained from this pin. This pin has to be connected to Ground 0V to enable the Transmission.
