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.

74LS00 Pinout, Configuration, Equivalent, Circuit & Datasheet

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. Even at this case output will be HIGH according to the truth table. Where high speed NAND operation is necessary. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. It is an irreplaceable datasehet for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.

Here we have connected two inputs to two buttons and output is connected to a LED. In case one of buttons is closed. The chip is available in different packages and is chosen depending on requirement. So 74LS00 can be used in high frequency systems.


With that the entire supply voltage appears across the transistor which is in OFF state. So we can make 74ls00 a four NOT gate chip if necessary. Use flip-flops to build a divider. When you want logic inverter. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.

Each gate can be used separately. We can use all four gates this way tosatisfy our needs.

After verifying the cases, you can tell that we have satisfied the above truth table. 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 internal connection of four gates is shown 74lw00. 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. Submitted dwtasheet admin on 3 April Under normal circumstances both buttons are not pressed and are open.


Use dividers to build a counter. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. It also analyzes transistor’s characteristics such as voltage and gain. The description for each pin is given below.

Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. This chip has less transition times which are needed for high speed applications.

Both transistors will be ON and voltage across both of them will be zero. The output waveforms can be both amplitude and frequency modulated.

Now let us consider a simple application circuit of the chip NAND gate. There are many reasons of using 74LS00 in electronic circuits. With these three cases we have realized the truth table for chip NAND gate.

With that both inputs of the gate will be LOW. When both inputs are HIGH: Also each gate has two inputs.

Here are a few examples where it 7l4s00 used. It is really popular and is available everywhere. In the case when any one input is HIGH: The 74xxyy ICs are logic gates of digital electronics.

So the total supply voltage appears across the transistors Q1 and Q2.
