Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. The output daatsheet can be both amplitude and frequency modulated. The 74xxyy ICs are logic gates of digital electronics. The chip is available in different packages and is chosen depending on requirement.

After verifying the cases, you can tell that we have satisfied the above truth table. With these three cases we have realized the truth table for chip NAND gate. Even at this case output will be HIGH according to the truth table.

It is an irreplaceable tool for troubleshooting and repairing electronic equipment by dwtasheet performance and health of electrolytic capacitors.


It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.

The internal connection of four gates is shown below. It is really popular and is available everywhere.

Here we have connected daatsheet inputs to two buttons and output is connected to a LED. With that the entire supply voltage appears across the transistor which is in 74l00 state. In case one of buttons is closed. In the case when any one input is HIGH: When you want logic inverter. This chip has less transition times which are needed for high speed applications. The description for each pin is given below. Use dividers to build a counter.

Where high speed NAND operation is necessary. With that both inputs of the gate will be LOW. You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.

Use flip-flops to build a divider. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.


Here are a few examples where it is used. It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc. When both inputs are HIGH: We can use all four gates this way tosatisfy our needs. So the total supply voltage appears across the transistors Q1 and Q2.

Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery. There are many reasons of using 74LS00 in electronic circuits. Submitted by admin on 3 April Now let us consider a simple application circuit of the chip NAND gate.

So we can make 74ls00 a four NOT gate chip if necessary. Also each gate has two inputs.

Under normal circumstances both buttons are not pressed and are open. TL — Programmable Reference Voltage.

This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.
