HT12E Encoder IC can be used only with its pair HT12D. These two ICs together form an Encoder and Decoder pair. The capa- bility to select a TE trigger on the HT12E or a. DATA trigger on the HT12A/B/C further en- hances the application flexibility of the 2. The content and copyrights of the attached material are the property of its owner. Distributed by: ✦

Simply put, HT12E converts the parallel inputs into serial output.
HT12E has a transmission enable pin which is active low.
ht12e ht12d datasheet – ht12e ht12d datasheet
This pin outputs the parallel data serially. 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.
The IC is has a wide range of operating voltage from 2. 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 datasheeet be set using the pins A0 to A7.
Choosing Motor For Robots. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. This IC hasmany applications in short range remote controlling. This is an CMOS logic integrated circuit encoder. These 12 bits are divided into 8 address bits and 4 data bits. I am now going to tell you about to control a certain ht21e wirelessly rather than eatasheet wires.
Interface SD Card with Arduino.
HT12A/HT12E – Product Details – Holtek
This pin has datashwet be connected to Ground 0V to enable the Transmission. Submitted by admin on 30 October They can also be connected to switches to manually send and receive data. This oscillator can be used by connecting these two pins through a 1M Resistor. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. You can know to set up the HT12D after this from here. These pins are generally shorted by a resistor. An LED can also be connected across this terminal to indicate output.
If you want security you can connect any of the 8 pins to 5V to make it high. Pull the Transmission Enable pin pin 14 to ground to activate transmission.

HT12E IC has four bit parallel data inputwhich it then converts to serial data output. We should set the bits in same pattern on Encoder and Decoder IC to pair them.
HT12E Encoder IC
So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. SPI Module of Arduino. Can range from 2.
Interface GPS with Arduino. Whenever an active low signal is applied at its TE pin then only the parallel data xatasheet transferred serially at the output, otherwise the IC is in high impedance state.
Gone are the days when we used to use wires to connect two devices to establish a communication path. Supply voltage; 5V 2.
These four pins are used to send data, the data daatasheet here will be decoded on HT12D IC sharing the same address bits. At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data. It is mainly used in interfacing RF and infrared circuits. In additional to itit also has 8 address lines which can generally be grounded along with the pin number 9. HT12E is an encoder integrated circuit of 2 12 series of encoders.
