HT12E Encoder IC

These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. HT12E is an encoder integrated circuit of 2 12 series of encoders. By continuing to use this website, you agree to their use. The primary function of HT12E is to encode a bit and send it out through the output pin. If you want security you can connect any of the 8 pins to 5V to make datxsheet high. This oscillator can be used by connecting these two pins through a 1M Resistor.

TL — Programmable Reference Voltage. Supply voltage; 5V 2.

You can know to set up the HT12D after this from here. So if you are working on a project off 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.


Interface GPS with Arduino.

Pull the Transmission Enable pin pin 14 to ground to activate transmission. SPI Module of Arduino.

Basically found in applications of remote control systems. It is mainly used in interfacing RF and infrared circuits. This IC has a total of 18 pinsnine on either sides: Transmission enable; active low.

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Used for interfacing RF circuits generally MegaHz. Now first of all let me acquaint you about these two integrated circuits: Can range from 2. The IC has a built in oscillator. The encoded bit can be obtained from the Dout pin pin HT12E has a transmission enable pin which is active low. Whenever an active low signal is applied at its TE pin then only the parallel data gets transferred serially at the output, otherwise the IC is in high impedance state.

Thus this helps in setting up oscillations in the IC. Virgin Galactic — Commercial Space Flight. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Hf12e or Fire alarm system etc.

They can also be connected to switches to manually send and receive data. In additional to itit also has 8 address lines which can generally be grounded along with the pin number 9. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. To find out more, including how to control cookies, see here: These two ICs together form an Encoder and Decoder pair.


This high-density System-in-Package SiP integrates controller, power switches, and support components. The Encoded 12 bit output data can be obtained from this pin. These are the 8-bit datashete bits, which is used to protect your data. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.

These 12 bits are divided into 8 address bits and 4 data bits. Connected to the Ground of circuit. This is an Og logic integrated circuit encoder. Submitted by admin on 30 October 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.
