Here are a few examples where it is used. 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.

So we can make 74ls00 a four NOT gate chip if necessary. Use dividers to build a counter. TL — Programmable Reference Voltage. With that the entire supply voltage appears across the transistor which is in OFF state. When both inputs are HIGH: It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.

It is a very dtaasheet 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. Each gate can be used separately. Under normal circumstances both buttons are not pressed and are open.


In case one of buttons is closed. Even at this case output will be HIGH according to the truth table. It is really popular and is available everywhere. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. 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.

Also each gate has two inputs.

The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. After verifying the cases, you can tell that we have satisfied the above satasheet table. With these three cases we have realized the truth table for chip NAND gate. The description for each pin is given below.

The 74xxyy ICs are logic gates of digital electronics. The output waveforms can be datasueet amplitude and frequency modulated.

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.

The chip is available in different packages and is chosen depending on requirement. There are many reasons of using 74LS00 in electronic circuits. With 74lz00 both inputs of the gate will be LOW. It also analyzes transistor’s characteristics such as voltage and gain.


Here we have connected two inputs to two buttons and output is connected to a LED. We can use all four gates this way tosatisfy our needs. Submitted by admin on 3 April When you want logic inverter.

The internal connection of four gates is shown below. Now let us consider a simple application circuit of the chip NAND gate. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. So 74LS00 can be used in high frequency systems. In the case when any one input is HIGH: So the total supply voltage appears across the transistors Q1 and Q2.

It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. Use flip-flops to build a divider. Both transistors will be ON and voltage across both of them will be zero.

Where high speed NAND operation is necessary. This chip has less transition times which are needed for high speed applications. The circuit includes an auto ranging as well as dagasheet switch and produces very accurate and stable readings.
