HT12E Encoder IC | HT12E Datasheet | Pin Diagram & Description

The Decoder receive the serial address and data from its corresponding decoder, transmitted by a carrier using an RF transmission medium and gives output to the output pins after processing the data.

Thanks for all your awnser, after studying a little bit into the RF module I found out my problem, the left side of both encoder and decoder are the Address PIN, which means they will ht1e communicate if those addresses are the same, that was what I was making wrong, I left them all at 1 and changed the resistors in them both cause the TX need to have 20 times the resistence of the receiver, in other words 50k and 1M resistors.

It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. Post as a guest Name. HT12E is an encoder integrated circuit of 2 12 series of encoders. I see you do not have jumpers to join each side of the power rails.


They are paired with 2 12 series of decoders for use in remote control system applications. For a better experience, please enable JavaScript in your browser before proceeding. Return and Refund Policy. Yah but I agree. Thanks a lot for helping us to maintain competitive prices. This ICs are paired with each other. Sign up using Facebook.

HT12E Encoder IC

More you buy, the more you get loyalty points and even further reduced prices for regular buyers. Also you will need to examine the data sheets for the “oscillator” setting resistor values, as the resistor values will be different for the transmiter and the decoder chip.

By buying this product you can collect up to 5 loyalty points. Replacement Transformer Started by ncag Today at 7: Last items in stock! For fun here is a free tool to help design, layout and simulate. Full Name Email Address. Thank you for replying.


Datasheets, Manuals or Parts. Best practice of using the breadboard is to use hh12d solid wire leads and neatly connect flush to the board without large inductive loops.


HT12E has a transmission enable pin which is active low. TB Stepper Motor Driver 4. Thread starter gerrard Start date Oct 15, Easy to Use, Versatile Robotics Kits I know but, and I’m going to sound like Olin here it should be easy to see how inconvenient it is, even for a new user.

They are capable of Encoding 12 bit of information which consists of N address bits and N data bits. The minimum purchase order quantity for the product is 1. Buy 15 or more pieces to get Free Shipping Option Availability: As soon as TE returns to high, the encoder output completes its final cycle and then stops.

Welcome to our site! What is Web Browser. Found this item with same quality and at a lower price but prefer to buy from robokits. Keep IC’s close toegether and imagine that it is a printed circtuit board layout.

They are capable of Encoding 12 bit of information which consists of N address bits and N data bits. We will notify you the result by email. Forums New posts Search forums. TQ for helping me sir.
