When both inputs are HIGH: In case one of buttons is closed.

With that the entire supply voltage appears across 74lx00 transistor which is in OFF state. Submitted by admin on 3 April Under normal circumstances both buttons are not pressed and are open. 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.

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. 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.


Even at this case output will be HIGH according to the truth table. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. So we can make 74ls00 a four NOT gate chip if necessary. In the case when any one input is HIGH: It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. So the total supply voltage appears across the transistors Q1 and Q2.

It also analyzes transistor’s characteristics such as voltage and gain. There are many reasons of using 74LS00 in electronic circuits. Here are a few examples where it is used. Also each gate has two inputs. The 74xxyy ICs are logic gates of digital electronics.

Use dividers to build a counter. With these three cases we have realized the truth table for chip NAND gate. With that both inputs of the gate will be LOW. Here we have connected two inputs to two buttons and output is connected to a LED. Each gate can be used separately. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.

Use flip-flops to build a divider. After verifying the cases, you can tell that we have satisfied the above truth table. The description for each pin is given below. So 74LS00 can be used in high frequency systems. We can use all four gates this way tosatisfy our needs.

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. TL — Programmable Reference Voltage. When you want logic inverter.

The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. Now let us consider a simple application circuit of the chip NAND gate.

The chip is available in different packages and is chosen depending on requirement.

The output waveforms can be both amplitude and frequency modulated. It is really popular and is available everywhere. This chip has less transition times which are needed for high speed applications. The internal connection of four gates is 74,s00 below. Where high speed NAND operation is necessary.

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

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.
