What is the price of the 74LS00 7400 74HC00 NAND Gate IC in Bangladesh?

The current price of the 74LS00 7400 74HC00 Quad 2-Input NAND Gate IC at KathalTech is ৳26.

How many NAND gates are inside a 74LS00 IC?

A standard 74LS00-family IC contains four independent 2-input NAND gates.

What does a NAND gate do?

A NAND gate produces a LOW output only when both of its inputs are HIGH. For all other input combinations, the output is HIGH.

What package does the 74LS00 use?

The listed 74LS00-family IC is commonly available in a 14-pin dual in-line package, known as DIP-14.

What is the difference between 74LS00 and 74HC00?

Both contain four 2-input NAND gates, but 74LS00 uses Low-Power Schottky TTL technology while 74HC00 uses high-speed CMOS technology. Their electrical characteristics and operating requirements differ.

Can the 74HC00 be used with Arduino?

Yes. The 74HC00 can be used in Arduino-based digital logic projects when its supply voltage and input/output logic levels are compatible with the circuit.

Why is NAND called a universal logic gate?

NAND gates can be combined to implement other fundamental logic functions such as NOT, AND and OR, making NAND a universal logic gate.

What are 74LS00 NAND gates used for?

They are commonly used for digital logic, switching, control circuits, timing circuits, latches, signal processing, educational experiments and microcontroller interface circuits.

Can a 74LS00 be used to make a NOT gate?

Yes. A NAND gate can function as a NOT gate by connecting its two inputs together and using the resulting output as the inverted signal.

Are 74LS00, 7400 and 74HC00 exactly the same?

They provide the same basic quad 2-input NAND logic function, but they belong to different logic families and can have different voltage, current, timing and logic-level specifications.

74LS00 / 7400 / 74HC00 Quad 2-Input NAND Gate

The 74LS00 / 7400 / 74HC00 family is a widely used digital logic IC containing four independent 2-input NAND gates. Each gate has two digital inputs and one output, allowing multiple logic operations to be performed using a single IC.

How a NAND Gate Works

A NAND gate is the inverse of an AND gate. Its output remains HIGH unless both inputs are HIGH.

Input A	Input B	NAND Output
LOW	LOW	HIGH
LOW	HIGH	HIGH
HIGH	LOW	HIGH
HIGH	HIGH	LOW

Universal Logic Gate

NAND is known as a universal logic gate because NAND gates can be combined to create other basic logic functions. This makes the 74LS00 family useful for designing a wide variety of digital circuits without requiring multiple types of logic gates.

Four Independent Gates

The IC contains four separate NAND gates, allowing several logic functions to be implemented with a single DIP-14 component.

It can be used to create:

NOT gates
AND gates
OR gates
Latches
Oscillators
Timing circuits
Logic control circuits
Digital switching circuits

DIP-14 Package

The DIP-14 through-hole package is convenient for breadboard prototyping, electronics education, circuit testing, and PCB assembly.

74LS00 vs 7400 vs 74HC00

These devices perform the same basic quad 2-input NAND function but belong to different logic families.

74LS00 – Low-Power Schottky TTL logic family.
7400 – Original/standard 7400-series logic designation; specifications depend on the exact manufacturer and variant.
74HC00 – High-speed CMOS logic family.

Operating voltage, input thresholds, propagation delay, output drive capability, and power consumption can differ significantly between these families. Always check the datasheet for the exact part number before designing a circuit.

Applications

The IC is suitable for:

Digital logic circuits
Boolean logic experiments
Logic gate demonstrations
Digital switching
Control circuits
Timing circuits
Latches and memory circuits
