The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. Also each gate has two inputs. TL — Programmable Reference Voltage. Where high speed NAND operation is 74ls000. Use dividers to build a counter.

74LS00 Datasheet PDF

The description for each pin is given below. Each gate can be used separately. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable xatasheet. After verifying the cases, you can tell that we have satisfied the above truth table. In the case when any one input is HIGH: 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.

With that both inputs of the gate will be LOW. Use flip-flops to build a divider. Under normal circumstances both buttons are not pressed datxsheet are open.


It also analyzes transistor’s characteristics such as voltage and gain. When you want logic inverter. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. We can use all four gates this way tosatisfy our needs. With that the entire supply voltage appears across the datasheey which is in OFF state.

Both transistors will be Dwtasheet and voltage across both of them will be zero. So the total supply voltage appears across the transistors Q1 and Q2.

74LS00 Pinout, Configuration, Equivalent, Circuit & Datasheet

This chip has less transition times which are needed for high speed applications. It is really popular and is available everywhere.

Now let us consider a simple application circuit of the chip NAND gate. The internal connection of four gates is shown below. With these dataeheet cases we have realized the truth table for chip NAND gate.

The chip is available in different packages and is chosen depending on requirement. So 74LS00 can be used in high frequency systems. Submitted by admin on 3 April Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.

74LS00 Datasheet

Here are a few examples where it is used. Here we have connected two inputs to two buttons and output is connected to a LED.


There are many reasons of using 74LS00 in electronic circuits. 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 output waveforms can be both 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.

Headphone amplifier is small enough 74os00 fit in Altoids tin box, and thanks to 74lz00 power consumption may be supplied from a single 9V battery. So we can make 74ls00 a four NOT gate chip if necessary. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.

When both inputs are HIGH: In case one of buttons is closed. Even at this case output will be HIGH according to the truth table. The 74xxyy ICs are logic gates of digital electronics.
