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

We can use all four gates this way tosatisfy our needs. Also each gate has two inputs. It also analyzes transistor’s characteristics such as voltage and gain. In case one of buttons is closed. Use dividers to build a counter. So the total supply voltage appears across the transistors Q1 and Q2.

The internal connection of four gates is shown below. Each gate can be used separately. TL — Programmable Reference Voltage.


74LS00 Datasheet

The description for each pin is given below. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. Use flip-flops to build a divider.

Both transistors will be ON and voltage across both of them will be zero. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. With that the entire supply voltage appears 7l4s00 the transistor which is in OFF state.

After verifying the cases, you can tell that we have satisfied the above truth table. When you want logic inverter. When both inputs are HIGH: Even at this case output will 74lss00 HIGH according to the truth table.

Submitted by admin on 3 April Here are a few examples where it is used. So 74LS00 can be used in high frequency systems.

Now let us datasjeet a simple application circuit of the chip NAND gate. With these three cases we have realized the truth table for chip NAND gate. 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.

Here we have connected two inputs to two buttons and output is connected to a LED. The 74xxyy ICs are logic gates of digital electronics.

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. This chip has less transition times which are needed for high speed applications. 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.


The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. 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.

There are many reasons of using 74LS00 in electronic circuits. The output waveforms can be both amplitude and frequency modulated. This LC Meter allows to measure 74ls000 small inductances making it dataheet tool for making all types of RF coils and inductors.

Under normal circumstances both buttons are not pressed and are open. It is really popular and is available everywhere.

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