Here we have connected two inputs to two buttons and output is connected to a 774ls00. The description for each pin is given below. Where high speed NAND operation is necessary. The meter is a perfect addition eatasheet any power supply, battery chargers and other electronic projects where voltage and current must be monitored.

There are many reasons of using 74LS00 in electronic circuits. Use dividers to build a counter. The chip is available in different packages and is chosen depending on requirement. Under normal circumstances both buttons are not pressed and are open. The internal connection of four gates is shown below. When both inputs are HIGH: With that the entire supply voltage appears across the transistor which is in OFF state.

Each gate can be used separately. Now let us consider a simple application circuit of the chip NAND gate. Both transistors will be ON and voltage across both of them will be zero. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.


With that both inputs of the gate will be LOW.

So we can make 74ls00 a four NOT gate chip if necessary. After verifying the cases, you can tell that we have satisfied the above truth table. So the total supply voltage appears across the transistors Q1 and Q2.

TL — Programmable Reference Voltage. 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.

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. It also analyzes transistor’s characteristics such as voltage and gain.

Also each gate has two inputs. It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such dataeheet oscillators, radio receivers, transmitters, function generators, crystals, etc. It is really popular and is available everywhere.

Submitted by admin on 3 April In case one of buttons is closed. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. Here are a few examples where it is used. In the case when any one input is HIGH: This 74lw00 has less transition times which are needed for high speed applications.


The 74xxyy ICs are logic gates of digital electronics. When you want logic inverter.

So 74LS00 can be used in high frequency systems. We can use all four gates this way tosatisfy our needs. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.

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. Even at this case output will be HIGH according to the truth table.

With these three cases we have realized the truth table for chip NAND gate. Arduino Prototype uses all standard through-hole components for easy construction, two ratasheet which are hidden underneath IC socket. Use flip-flops to build a divider.

The output waveforms can be both amplitude and frequency modulated. This LC Meter allows to measure incredibly small inductances making datasehet perfect tool for making all types of RF coils and inductors.
