HT12E DATASHEET PDF

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: ✦

To find out more, including how to control cookies, see here: The 4-bit data datasheeg 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. This pin has to be connected to Ground 0V to enable the Transmission. The IC is has a wide range of operating voltage from 2.

SPI Module of Arduino. Generally a resistor of value 51 KOhms can be used. In additional to itdatasheet also has 8 address lines which can generally be grounded along with the pin number 9. HT12E IC has four bit parallel data inputwhich it then converts to serial data output. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.

The primary function of HT12E is to encode a bit and send it out through the output pin.

This oscillator can be used by connecting these two pins dataxheet a 1M Resistor. Skip to content Gone are the days when we used to use wires to connect two devices to establish a communication path.

HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. Pull the Transmission Enable pin pin datxsheet to ground to activate transmission. They are paired with 2 12 series of decoders for use in remote control system applications. Now first of all let me acquaint you about these two integrated circuits: At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data.

HT12E Encoder IC

A basic connection diagram for the HT12E IC is shown below In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Basically found in applications of remote control systems. After one complete cycle datasheey data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer.

Simply put, HT12E converts the parallel inputs into serial output.

HT12E has a transmission enable pin which is active low. The Encoded 12 bit output data can be obtained from this pin. Connected to the Ground of circuit. These 12 bits are divided into 8 address bits and 4 data bits.

We should set the bits in same pattern on Encoder and Decoder IC to pair them. Skip to main content. HT12E is an encoder integrated circuit of 2 12 series of encoders. This high-density System-in-Package SiP integrates controller, power switches, and support components.

Submitted by admin on 30 October So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. This is an CMOS logic integrated circuit encoder.

An LED can also be connected across this terminal to indicate output. 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. Transmission enable; active low. Can range from 2. Choosing Battery for Robots. These are the 8-bit address bits, which is used to protect your data.

You can know to set up the HT12D after this from here. Supply voltage; 5V 2.

HT12E Datasheet

This IC hasmany applications in short range remote controlling. Gone are the days when we used to use wires to connect two devices to establish a communication path. This cycle is repeated as long as TE is kept low. By continuing to use this website, you agree to their use. 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. These pins are generally shorted by a resistor.

This IC has a total of 18 pinsnine on either sides:
