You might have come across different ICs over the years, but the ultimate HT12D is among the most common ICs that you can find in the market. Not only this, it is compatible with HT12E encoder, and different experts have different takes on both these devices. The debate of IC HT12E vs. HT12D will never end. However, we will try to look at these in a fun and easy way to render you the necessary knowledge about them through this post. The HT12D comes under the groups of CMOS LSis. 

There are different applications of these around us. There is a definite number of bits present in these, which help in seamless data processing. Therefore the bits come together to efficiently make the home appliances and smart home appliances work for a random user. When we talk about telecommunications, we need to understand that one end is for receiving signals while the other end is for transmitting them. 

Today, we dedicate this post to the IC ht12e Vs. ht12d decoder for you. Let’s get started!

Characteristics of ht12d decoder

Before we start our discussion, we need to understand the salient features and specifications of HT21D:

• You can rely on HT21D when working with huge amounts of voltage, which is why it is much more feasible to use compared to other versions.
• You can easily connect it with the readily available 12-N bits encoder that many other versions dont allow at all. 
• You can adjust the current easily with this encoder as well. 
• You will find a huge range of packages for the HT21D encoder. 

Where to use HT12E?

By far, you know that we can combine HT21D and HT21E for our operations. However, we need to know the correct method of doing this work out in all scenarios. There are some similarities between the two. Their bits are the same, which is an 8-bit setup. These are both reliable for RF applications. The precise distribution of bits in the transmitting and addressing takes place among these encoders.

How to use the HT12E decoder?

You cannot expect great results by following the incorrect methods in telecommunications. The same applies to the working of HT21E. In this section, we will explain how you can use this encoder in an accurate way to get desired results. Experts believe that such encoders give users an edge over others due to their features. 

Its 12 bits are highly important to consider when we talk about data transmissions. Therefore it proves to the best to include in the radios to experience more precision in their performance. You first need to adjust the operating voltage for this encoder. Keep it up to 12V while the minimum will be 2.4V. You also need to pay attention to the pins so that you won’t have to face any complications. Now work on the Transmission Enable Pin so that it can begin with the transmission. An oscillator is also important for this entire setup. But there is no need for an external oscillator since you will find an oscillator attached to this encoder already. Also, dont forget to turn on the pins of the oscillator. The distribution of the bits will take place among the pins, and the setup will start working. 

Applications of HT12E 

• No wireless communication setup can work precisely without the inclusion of an industrial-grade HT21E encoder. 
• It is important for the seamless working of IR systems and RF applications. 
• These circuits are also reliable to use with the in-built remote control system to provide technicians with ease and save them time. 
• It is crucial for remote switching and finds important applications in consumer electronics and smart home appliances. 
• You can even use this in the fire alarm, alert systems, and smoke alarms, where it plays the role of a lifesaver in case of emergency. 

Characteristics of HT12D

It’s time to discuss the features of HT21D, and below, you will find the remarkable properties that make it crucial for RF applications and many others. Let’s take a look!

• Despite the fact that you can work with its default 5V voltage but you can also increase it as per your case. It can extend up to 12V in total. 
• Using this encoder with an increased voltage is crucial for smart applications and complex electronics.
• It also features a specific temperature range that is optimum for its fine performance. 
• There is no problem if you want to combine it with an HT21E encoder because both encoders dont influence each other negatively. 
• There is also no need to attach an external oscillator with it because it comes with its own oscillator, which makes the assembling much easier. 
• The direct interfacing through this encoder in the RF systems makes it even more crucial for telecommunications.
• You can test it on the basis of different amounts of current as well. 
• There are more chances that encoders like these will work on their own without requiring additional help. 

Working of HT12D

The main role of an encoder like HT21D is to make seamless data processing within 12 bits possible. A special input pin is also involved in this process. The best part about this encoder that experts often mention is its oscillator which makes the transmission a lot easier. 

Steps

1. The first step is to determine the voltage of pin 18 and keep it at 5V while pin nine is grounded. 
2. Now work on the oscillator pins and carefully determine their individual voltages. It will make the encoder do its job seamlessly.
3. The distribution of the bits will take place after this step. 
4. Also, setting the address of these pins is also crucial depending on the 8 bits. Also, you need to know that you can adjust them on the basis of high and low states since there is no in-between. 

Conclusion

This will be all for today. We hope that we have provided you with clear-cut information on the most important encoders, HT21E and HT21D, through this post. Also, you can easily learn to make them work efficiently through the instructions mentioned. Their features are different; therefore, these encoders are application-specific. Make sure to stick to the guidelines before proceeding with them.
