HT12E PDF

HT12E Encoder IC can be used only with its pair HT12D. These two ICs together form an Encoder and Decoder pair. Buy HOLTEK HT12E online at Newark element Buy your HT12E from an authorized HOLTEK distributor. HT12E is a series encoder IC (Integrated Circuit) for remote control applications. It is commonly used for radio frequency (RF) applications. By using the.

They can also be connected to switches to manually send and receive data.

The encoder will be in the Standby mode when the transmission is disabled. These 12 bit parallel data is divided in to 8 address bits and 4 data bits. 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.

HT12E Encoder IC for Remote Control Systems

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. You can know to set up the HT12D after this from here. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.

When the transmission enable TE signal switches to HIGH, the encoder output completes the gt12e cycle and stops as shown above. It is very important that your Decoder should also have this same address for them to talk to each other.

The primary function of HT12E is to encode a bit and send it out through the output pin. So if you are working on a project which has to transmit a 4-bit data from one jt12e to other either by wire or wireless then this IC pair will be best suited for you. This pin has to be connected to Ground 0V to enable the Transmission.

Transmission Timing for HT12E. Ht12s is able to operate in a wide voltage range from 2. Top menu About Us Advertise. By using the paired HT12E encoder and HT12D decoder we can easily transmit and receive 12 bits ht122e parallel data serially. The Encoded 12 bit output data can be obtained from this pin. Optical Transistors Out of Silicon: The HT12E 2 12 series encoder starts a 4 word transmission cycle upon receiving transmission enable signal on TE input.

Working Flowchart of HT12E. If you want security you can connect any of the 8 pins to 5V to make it high. These four pins are used to send data, ht122e data encoded here will be decoded on HT12D IC sharing the same address bits.

Skip to main content. HT12E — Block Diagram. These two ICs together form an Encoder and Decoder pair. It is commonly used for radio frequency RF applications.

HT12A/HT12E – Product Details – Holtek

For some time now Intel had been trying to enter the smartphone sector owing to the success when it Can range from 2. The IC is has a wide range of operating voltage from 2. This oscillator can be used by connecting these two pins through a 1M Resistor. 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.

Its power consumption is very low, standby current is 0. So out of hh12e bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. HT12E simply converts 12 bit parallel data in to serial output which can be transmitted through a RF transmitter.

The IC has a built in oscillator. A team of researchers from University of Pennsylvania led by Nader Engheta are working on the ways to use We ht122e set the bits in same pattern on Encoder and Decoder IC to pair them.

We all know that a Solar Panel can be used to convert light energy to electrical energy.
