Hello everyone! I hope you all will be absolutely fine and having fun. I am going to give you a detailed Introduction to CD4051 today. CD 4051 is an analog multiplexer and demultiplexer. It has very low OFF leakage current and low ON impedance. Over full voltage ranges, very low power is dissipated by CD-4051.
CD-4051 is an eight (8) channel multiplexer and has three control input named as A, B and C. These inputs connect only 1 out of 8 channels to the output in order to obtain the desired output. Channel I/O terminals became outputs and common O/I become input terminals when CD 4051 is used as a demultiplexer. CD-4051 has a lot of amazing features e.g. binary address decoding on chip, break before make switching eliminates channel overlapping, ...

PC 817 has an internal LED and a photo transistor. The photo transistor's base becomes activate when LED throws light on it. The output obtained can be divided into two formats either common emitter or common collector. But the configuration is ...
Hello everyone! I hope you all will be absolutely fine and having fun. I am going to elaborate you on Introduction to LT1054. It is a monolithic device. LT-1054 is also known as voltage regulator and bipolar capacitive voltage converter. Its mean feature is that it provides very low voltage losses as compared to the other common converters. LT 1054 also provides large output currents in comparison to general converters. It provides a voltage drop of around 1.1V while operating at 100mA.
LT 1054 provides us with a feature of regulation. This feature was not available in earlier voltage converters. We can get a regulated output just by inserting an external resistance. We can shut down LT-1054, if we ground its feedback terminal. Its internal osci ...
Hey Guys! Hope you are doing great. Today, I am going to discuss the details on the Introduction to BJT (Bipolar Junction Transistor). It is an electronic component mainly used for amplification and switching purpose. As the name suggests, it is composed of two junctions called emitter-base junction and collector-base junction.
Don't confuse BJT with regular transistors. A transistor is a semiconductor device, comes with three terminals that are used for external connection with electronic circuits. A transistor is termed as a trans resistor which is used as switch or gate for electronic signals. Small signals applied between one pair of its terminals are used to control much larger signals at the other pair of terminals.
Actually, transistors are divided into two categories called u ...

Hello readers, hope you all are doing great. In this tutorial, we will discuss low power modes in ESP32, their purpose and their implementation to increase the battery life by reducing power consumption.
Purpose of Low Power Modes
Fig.1
Along with multiple wireless and processing features, ESP32 also provides us with a power-saving feature by offering sleep modes. When you are powering the ESP32 module from the live supply using an adaptor or a USB cable, there is nothing to worry about power consumption. But when you are using a battery, as a power source to ESP32, you need to manage the power consumption for longer battery life.
Low Power Modes in ESP32
When ESP32 is in sleep mode, a small amount of power is required to maintain the state of ...
Hello Friends! Hope this finds you well. I welcome you on board. Thank you for clicking this read. In this post today, I’ll walk you through the Introduction to BD140.
BD140 is a medium power bipolar junction transistor that is mainly used for switching and amplification purpose. It belongs to the PNP transistor category and comes in the TO-126 package. It is made up of silicon material with collector current 1.5A which indicates it can support loads under 1.5A. The collector-base and collector-emitter terminal voltages are 80V and emitter-base voltage is 5V which is used to bias the transistor.
In this post, I’ll be detailing the complete introduction to BD140 covering pinout, working, absolute maximum ratings, physical dimensions, alternatives ...
Hello Friends! Hope you are doing well. I am back to give you a daily dose of valuable information. Today, I'll discuss the detailed Introduction to RS 232 which is a standard communication protocol mainly used for serial communication between two devices. It was first introduced by the EIA (Electronic Industries Association) in 1960 to provide a pathway for connecting one device with other peripheral devices for flawless digital communication.
It is true, that the inception of USB has grossly reduced the need for RS232 protocol, still, we can't brush off its significant importance in some industrial applications where Programmable Logic Controllers and Computerized Numerical Control Equipment are specifically programmed using RS 232 connectors ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give a detailed discussion on Introduction to LM4040. LM-4040 is specially designed for an accurate micro-power shunt voltage reference. These voltage references includes the standards of 2.5V, 3V % 5V respectively. LM-4040 has three different grade A, B and C grades and they have o.1%, o.5% and 1% tolerances respectively.

We can achieve an excellent performance from this device when it is operating at the current ranging from 60uA to 15mA and its temperature coefficient is 20 ppm per degree. In order to maintain good stability ...
Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give an Introduction to 1N4148. It is basically a diode used for fast switching purposes. Switching diodes are usually single P-N diodes and their functionality is similar to that of normal switch.
Below a specific voltage, switching diodes i.e. 1N4148 has high resistance. Whereas as above that specific voltage they show a low resistance. It is a most commonly used diode due to its smaller size, easy availability and low cost. Good switching diode can be chosen by its maximum reverse recovery time and its power dissipation ranging from 80mW to 1kW. Switching diodes such as 1N4148, 1N4007 etc. have very wide range of applications specially in Embedded Systems ...
