Also each gate has two inputs. Here we have connected two inputs to two buttons and output is connected to a LED. So 74LS00 can be used in high frequency systems. It also analyzes transistor’s characteristics such as voltage and gain.

74LS00 Pinout, Configuration, Equivalent, Circuit & Datasheet

This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. Under normal circumstances both buttons are not pressed and are open. Submitted by admin on 3 April 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 74xxyy ICs are logic gates of digital electronics.


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, 74lx00, 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.

So the total supply voltage appears across the transistors Q1 and Q2. When both inputs are HIGH: With that both inputs of the gate will be LOW. There are many reasons of using 74LS00 in electronic circuits.

Use dividers to build a counter. In the case when any one input is HIGH: Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. 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. The internal connection of four gates is shown below. This chip has less dtasheet times which are needed for high speed applications.

datassheet It is really popular and is available everywhere. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. Each gate can be used separately.

With that the entire datadheet voltage appears across the transistor which is in OFF state. Where high speed NAND operation is necessary.


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.

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. With these three cases we have realized the truth table for chip NAND gate. Here are a few examples where it is used. 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. TL — Programmable Reference Voltage. So we can make 74ls00 a four NOT gate chip if necessary. 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. Use flip-flops to build a divider. When you want logic inverter. Even at this case output will be HIGH according to the truth table.

The output waveforms can be both amplitude and frequency modulated. The description for each pin is given below.

Both transistors will be ON and voltage across both of them will be zero.
